This article aims at the investigation of the effect of five different parameters on the transport behavior of PP/jute yarn commingled eco-composites. The high affinity of jute yarns to moisture (hydrophilic nature) favored the water absorption whereas xylene and toluene diffusion through PP/jute commingled system reduced with increasing fiber content. Chemical treatments increased the interfacial adhesion between the matrix and jute yarns resulting in lesser number of voids and other irregularities at the interface and also resulted in a reduction in the hydrophilic tendency of jute yarns. This led to a decrease in apparent weight gain % with different treatments. The activation energy for the solvent xylene increased with the increase in fiber content owing to the hindering of motion of the solvent molecules by the reinforcing jute yarns whereas for the solvent water, the activation energy decreases with increase in fiber content due to the hydrophilic nature of jute yarns. The analysis of mechanism of transport revealed that the diffusion of water through the composites very nearly follow Fickian mode of transport whereas for the solvent xylene it deviates from it. © 2017 Society of Plastics Engineers.

Dr. Saritha A. and Joseph, K., “Role of solvent interaction parameters in tailoring the properties of chlorobutyl rubber nanocomposites”, Polymer Composites, vol. 37, pp. 353–359, 2016.[Abstract]


Chlorobutyl rubber, a special class of butyl rubber, which exhibits superior air impermeability, is the elastomer of choice for the inner tubes and liners of tires. Chlorobutyl rubber nanocomposites containing layered silicates were prepared using solvents with varying cohesive energy density and the effect of solvent–clay and solvent–rubber parameters in determining the properties of the nanocomposites were studied. The nanocomposites so prepared were characterized by X-ray diffraction, scanning electron microscopy and transmission electron microscopy. The results were interpreted with the help of thermodynamic concepts and a correlation between the mechanical properties of the nanocomposites and the difference in the interaction parameters was done. The same correlation was then applied to gas barrier properties and trends identical to mechanical properties were observed. Thereby it was shown that a strong relationship exists between properties of a system and solubility parameters in solution mixing process. POLYM.

Green synthesis of nanoparticles has become a prominent area of interest in the field of nano science and technology, as it is a non toxic, economically viable and green approach. In the present work we have developed an ecofriendly and zero cost approach for the green synthesis of silver nanoparticles using cashew nut peel. The well known characteristic phenomenon of surface Plasmon resonance (SPR) has been exploited towards the characterization of the green synthesized nanoparticles. The nanoparticles were characterized by UV spectroscopy and the behavior of these particles towards naked eye detection of metal ions were observed. The sensitivity of the nanoparticles towards the detection of metal ions were carefully monitored by the shift in the SPR band. Moreover the larvicidal potential of these green synthesized silver nanoparticles were evaluated as per WHO standards. Such a route of green synthesis of silver nanoparticles is economically feasible as well as environment friendly and also capable of rapid synthesis of nanoparticles at ambient conditions.

The dynamic mechanical properties of chlorobutyl rubber nanocomposites containing different varieties of clay have been investigated. The clay moieties have been chosen so that they vary in their organic modification, modifier concentration, and d spacing. The viscoelastic properties such as storage modulus, damping behavior, and loss modulus of polymer composites depends on matrix filler interaction, crystallinity, and extent of crosslinking. The prepared composites were characterized by X Ray Diffraction, and the extend of exfoliation/intercalation was studied. It has been observed that the storage modulus of the composites increased with the addition of filler due to the enhancement in stiffness of the material. The damping behavior was found to decrease with the addition of filler and this was attributed to the restricted movement of the polymer segments. The higher surface area to volume ratio of the layered silicate resulted in the better interaction between the polymer matrix and filler. The variation of loss as well as storage modulus of the nanocomposites were evaluated as a function of filler loading, and a comparison of the properties of the rubber nanocomposites containing different organic clay was also carried out. Finally, a calculation of constrained volume of polymer chains was done in the nanocomposites. POLYM. COMPOS., 36:2135–2139, 2015. © 2014 Society of Plastics Engineer More »»

Green nanotechnology has gained momentum in the recent years because it couples the immense applications of nanotechnology with the principles of green chemistry so that the toxic effects of nanotechnology stands nullified. The environmental as well as health issues of nanotechnology has only been addressed in the recent times and since then the green pathway towards the synthesis of nanoparticles has gained immense attention. The novel phenomenon of surface Plasmon resonance exhibited by metallic nanoparticles has been exploited and silver nanoparticles were prepared from biowastes like cashew peel, tapioca peel, banana bosom peel etc which would otherwise appear as waste in and around the processing centers.

Nanocomposites were prepared using montmorillonite with different organic modifiers (cloisite 10 A, cloisite 15 A, and cloisite 20 A) and the effect of intercalant structure on clay morphology and chlorobutyl vulcanization kinetics was investigated. Because of its lower rigid structure the aliphatic salt was easier to intercalate into the clay galleries giving rise to a higher interlayer distance and facilitating the rubber intercalation obtaining an exfoliated structure in the nanocomposite. The vulcanization process was sensibly accelerated by this organoclay and a higher crosslinking degree was observed in the nanocomposite which gave rise to materials with improved processing and physical characteristics. The present work focuses on characterising the surfaces of organically modified MMT clays and the relationship to the final properties of their nanocomposites. Concentrating on the surface modifiers, one has to take into account their interaction with the matrix polymer, the solubility of the organic molecule adding to the complexity due to its influence. We aim to show that understanding the influence of surface characteristics is the basis for selecting the ideal organoclay for the given matrix polymer. Depending on the nature of the surfactant used for the organic modification of clay and its modifier concentration the nanocomposites exhibit difference in the properties. The organoclays used in the present study were selected to explore the effects of the amine surfactant structure on the dispersion of clay particles in chlorobutyl rubber matrix. The structure of the organic amine compound used to form the organoclay is expected to have some effect on the morphology and properties of the nanocomposites. © 2011 Wiley Periodicals, Inc.

The field of polymer nanocomposites has attracted attention as a method of enhancing polymer properties and extending their utility by using molecular or nanoscale reinforcements rather than conventional particulate filled nanocomposites. These materials exhibit behavior different from conventional composite materials with micro scale structure due to small size of structural unit and high surface to volume ratio. Chlorobutyl rubber nanocomposites were prepared using organically modified cloisite 15 A and characterized using XRD and TEM. The gas barrier properties of the nanocomposites were modeled using the composite theories of permeation and the tortousity factors were predicted. Analysis of mechanical properties, transport and gas barrier properties of the nanocomposites as well as the calculation of break through times show the effectiveness of the material to be utilized as potential gas as well as VOC barrier materials. © 2012 Elsevier Ltd.

The mechanical and thermophysical properties of TiO2-filled chlorobutyl rubber composites were investigated. These materials exhibited enhanced mechanical properties such as increased modulus, tensile strength, and hardness. The morphology of filler dispersion in the matrix was analyzed by scanning electron microscopy and atomic force microscopy. Moreover, the effect of TiO2 content on the molecular transport of solvents was examined by means of degree of swelling, volume fraction of rubber, penetration rate of solvent, mean diffusion coefficient, etc. A periodic method was used to estimate the thermophysical behavior of samples. It was shown that the thermal conductivity and diffusivity of composites increase with increasing of TiO2 filler content. Finally, the utilization of the material as effective chemical protective clothing against volatile organic chemicals was analyzed. POLYM. COMPOS., 2011. © 2011 Society of Plastics Engineers

K. Y. Sandhya, Dr. Saritha A., and Joseph, K., “Liquid Crystalline Polymers from Renewable Resources: Synthesis and Properties”, in Liquid Crystalline Polymers: Volume 1–Structure and Chemistry, K. Vijay Thakur and R. Kessler, M. Cham: Springer International Publishing, 2016, pp. 273–306.[Abstract]


Materials from renewable sources are attracting immense attention due to the excellent properties and ecological advantages it can offer and due to the growing environmental concerns. Liquid crystalline polymers (LCP) from renewable sources have engrossed considerable attention during the past few decades. Nowadays, agro based renewable materials are the subject of a growing number of academic and industrial research projects, because of diminishing fossil resources combined with the increasing environmental concern of petroleum based polymers. Renewable resources such as cellulose, vegetable oils and other plant and animal originated products are ideal alternatives to provide base chemicals for various materials, as they are abundant throughout the world and contain several reactive chemical sites such as double bonds, allylic carbons, ester groups, and the alpha carbons of the ester groups, which can be used for polymerization. LCPs can be successfully synthesized from a good number of natural sources including cardanol, castor oil and can be derived from biopolymers such as cellulose, DNA, proteins etc. The study of liquid crystal phases of cellulosic esters and ethers become attractive owing to their properties such as toughness and processability. Cardanol obtained from cashew nut shell liquid possesses functional groups for creating polymers and has interesting structure for exhibiting liquid crystalline properties. Cardanol based LCP can form cross linked network polymers due to the unsaturation of side chains and possibly can freeze the liquid crystalline phase. On the other hand liquid crystal properties of cellulose in electro optical applications open new horizons for these traditional materials. A milestone in the development of nano cellulose science and technology is the discovery of cellulose nano crystals (CNC) from natural cellulose sources. CNC is made from cellulose which is a natural polymer of wide abundance and is an almost non-exhausting source. These nanofibrils under particular concentration can form ordered structures leading to lyotropic liquid crystals. It was noticed that rod like CNC can form a stable chiral nematic liquid crystalline phase. The chiral nematic (cholesteric) phase thus formed is characterized by long-range orientational order of the nanorods combined with a helical modulation of the direction in which they align. The intriguing ability of CNCs to self-organize into a cholesteric liquid crystal phase with a helical arrangement has attracted significant interest, as this arrangement gives dried CNC films a photonic band gap. Thus formed film has attractive optical properties, creating possibilities for use in applications such as security papers and mirrorless lasing. Controlling and understanding the mechanisms of liquid crystalline self-assembly of LCPs are not only of fundamental importance but are steps along the route to produce novel materials with desirable optical or mechanical properties. Nanostructured films with a photonic band gap phase of CNC suspensions arising from the spontaneous helix formation in the cholesteric liquid crystal have been the focus of several studies. The use of CNC suspension as a self-assembled template for the synthesis of inorganic materials offers a promising and versatile platform to fabricate multifunctional mesoporous materials with photonic crystal properties of very large surface areas. The combination of CNC and inorganic materials with higher refractive indices may lead towards photonic devices such as tunable mirrorless lasers, and CNC-templated materials with specific surface functionalities may pave way for the development of enantioselective sensors. In the proposed chapter we would discuss the different methods of synthesis of LCPs using renewable sources like cellulose, cardanol etc., chemical functionalization and characterization of cellulose, nano cellulose and their derivatives and their subsequent self organization into LCPs. The structural as well as phase transitions will be discussed in detail with various characterization techniques. A brief overview on the future scope of research and applications in the aforementioned field will also be given. More »»
