Abstract

This study was conducted to see the effect of a mixture of ZnS nanoparticles and PVA on the properties of nanocomposite PV / ZnS. Mixing is done with the sol-gel method, which dissolve ZnS nanoparticles and PVA with distilled water. Stirring is done through the magnet, with the angular velocity of 500 rpm, and heated at 80 ° C temperature. The solution that has been shaped gel then put into molds and then cooled naturally. Variations mixture of PVA: ZnS is (100:0)%, (99:1)%, (98:2)%, (97:3)% and (96:4)%. The results of mechanical tests showed that the average maximum tensile strength of 34.390 MPa obtained on the composition of the mixture of PVA: ZnS at (100:0)%, the average maximum elongation at break of 430.81% was obtained on the composition of the mixture of PVA: ZnS at (99 : 1)%, the average elastic modulus of 190.73 MPa maximum obtained on the composition of the mixture of PVA: ZnS at (98:2)%. This result is better because it is more equitable in terms of mixing and content conforms to the crosslinking better. DSC results obtained on the composition of the maximum melting temperature of PVA: ZnS at (97:3)% which is at a temperature of 224.39 ℃.
