STUDY OF FREE VOLUME IN POLYMER BLENDS BY PALS
Main Article Content
Abstract
Blends of polysulphone (PSF) and poly (methylmethacrylate) (PMMA) have been prepared by using solution cast technique. The change in free volume in the blends of polysulphone and poly (methylmethacrylate) is characterized by Positron Annihilation Lifetime measurements. Here we are showing the change in free volume density in the blends. The increase in intensity (I3) component in blend of PSF and PMMA shows the increase in free volume density. Optical micrographs of the blends have been taken to get an insight of the morphology of the blends. The resulting blends of PMMA and PSF are found to be of immiscible category.
