Abstract

Abstract: ZnO nanoparticles were in-situ grafted with PMMA from the surface and used as a modifier for PVC. Such ZnO nanoparticles were homogeneously dispersed in the PVC matrix. Filled with PMMA grafted ZnO nanoparticles, PVC composites possessed a tensile strength of 78 MPa , which was 35% higher than that based on untreated ZnO; and an impact strength 13.6 kJ•m-2, twice as untreated case. In addition, PMMA grafted ZnO nanoparticles imparted PVC a perfect UV-shielding property.

Key words: nano-ZnO, poly(vinyl chloride), graft surface modification, UV-shielding properties, mechanical property
