Abstract

Effect of Graphite and Copper Nano-Particles on Free Volume Properties of PVC/NBR Blends Studied by Pal Spectroscopy

Ehsan Gomaa* and Emad Hassan Ali

Positron Annihilation Lifetime (PAL) spectroscopy has been used to investigate the effect of different concentrations of graphite and copper nano-particles in polyvinylchloride (PVC)/ butadiene-acrylonitrile copolymer (NBR) blends on free volume properties of PVC/NBR nano composites. However, the miscibility of PVC/NBR blends was investigated. The free-volume properties showed a negative deviation from linear additive relationship indicating miscibility of two blends. In additions, this research to confirm the results of the previous study on the same samples through the correlation between positron annihilation parameters and some of the properties studied.
