Abstract


CdS/PVC and ZnS/PVC nanocomposites were prepared by solution mixing taking different wt. % (2, 4, 6 & 8) of CdS and ZnS nanopowders synthesized through the wet chemical method respectively. The morphology of these nanocomposites has been characterized using transmission electron microscopy. The dynamic mechanical analyzer (DMA) was used to study the storage modulus and Tan δ of CdS/PVC and ZnS/PVC. The variation of storage modulus and glass transition temperature for CdS/PVC and ZnS/PVC nanocomposites with filler content has been explained on the basis of dispersion of nano fillers.  An effort has also been made to determine the glass transition activation energy using Vogel-Fulcher-Tammann (VFT) equation. Effect of CdS and ZnS nanoparticle concentration on glass transition activation energy has been discussed
