Abstract:

The current paper discusses the effect of three different nano fillers on the microstructure, mechanical, thermal and sorption properties of polypropylene (PP) composites. The composition of nanofillers (nanosilica (N), multiwalled carbon nanotubes (MWCNT) ,halloysite nanotubes (HNT)) in PP hybrid composites are maintained at 3 wt% and micro filler (glass fiber) is fixed at 20 wt%. The dispersion of micro and nano scale reinforcing fillers are analyzed using Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy(TEM). The composite comprising of glass fiber and MWCNTs exhibited highest tensile strength and modulus by 79% and 145% respectively in comparison with neat PP. The HNT reinforced hybrid composite presented better resistance to the permeability of the solvent due to the tortuous flow path offered by high aspect ratio filler. The Differential Scanning Calorimetry (DSC) analysis revealed that CNTs acts as heterogeneous nucleating agent and promotes enhanced crystallization in comparison with other fillers.
