USE OF EXPANDED PERLITE AS GREEN FILLERFOR THE PREPARATION OF POLYVINYLCHLORIDE/PERLITE COMPOSITE

The present study investigated using expanded perlite (EP), as an affordable and environmentally friendly filler for polyvinyl chloride.The oxidative chlorophosphorylation (OxyCh) reaction was used for preparing EP/PhPVC composite.To evaluate the effect of EP on the composite's mechanical, electrical, and physical characteristics, the PhPVC (without EP) have been obtained too.A comprehensive comparison methods were carried out on optical and electrical properties of PhPVC and, EP/PhPVC.Ultraviolet-visible spectrophotometric analysis (UV-vis) demonstrated the differences between measured optical bandgap energy (Eg) of both PhPVC and EP/PhPVC.It shows that owing to its enhanced adsorption capacity and better electro-optical properties, these materials are expected to find a suitable role in various practical applications.
