This investigation highlights the processing of Nylon 66 and the incorporation of nano-silicate into the Nylon 66 polymeric matrix. Further, radiation modification of Nylon 66 and nano-silicate dispersed Nylon 66 was carried out in order to essentially alter the physicochemical properties of the material. A combination of both the above methods of processing and modifying the neat Nylon 66 polymeric matrix provides an interesting aspect for studying the resultant effect on the variation in properties of the composite material over the virgin polymer. There was a significant improvement of physicothermal and physicomechanical properties when Nylon 66-silicate nanocomposites were further modified under gamma radiation, which was confirmed by differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), tensile and water absorption studies.
