Synthesis and morphology of polyvinyl alcohol/zinc sulfide nanocomposite

Abstract

Polyvinyl alcohol (PVA) nanocomposites have been synthesized. The nanocomposites which prepared by sol-gel method were mixed to various concentrations of PVA using magnetic stirrer bar of 500 rpm at 80°C. After the solvent evaporates, the white suspensions were casted on to a flat metal and the film-like composites formed. Those samples were characterized including tensile for mechanical test follow ISO-527-2 and melting points for thermal analysis using DSC operated at 20°C/min with the temperature range of 30-300°C. The most homogeny and Young modulus samples were obtained at ratio 98:2 w/w % of PVA/ZnS, and the highest melting point were found at ratio 97:3% of PVA/ZnS.
