Abstract

Organic-inorganic hybrid nanocomposites composed of poly(methyl methacrylate) and Al₂O₃ nanoparticles (PMMA-g-Al ₂O₃) were prepared through a facile surface thiol-lactam initiated radical polymerization (TLIRP) using grafting from strategy. The surface of Al₂O₃ nanoparticles (Al₂O ₃ NPs) was modified by (3-mercapto)propyl trimethoxysilane in order to prepare thiol functionalized Al₂O₃ NPs (Al ₂O₃-SH). A controlled radical polymerization of MMA was conducted to afford covalently bonded PMMA with Al₂O₃ NPs in the presence of Al₂O₃-SH and butyrolactam. The surface functionalization, bonding nature, morphologies, thermal and physical structure of PMMA-g-Al₂O₃ nanocomposites were investigated by FT-IR, XPS, EDS, SEM, TGA, DSC and DLS analyses. The controlled nature of the TLIRP of MMA from the surface of Al₂O₃-SH was ascertained by GPC analysis.
