文摘

In-situ emulsion polymerization and alcoholysis reaction is a good method to prepare GO/PVA nanocomposites. Surface chemical grafting modification of GO with PVA chains was also carried out during the in-situ emulsion polymerization and alcoholysis reaction. The surface chemical grafting modification of GO by in-situ polymerization and alcoholysis reaction could not only improve the dispersion of fillers in matrix, but also the interfacial interactions between fillers and matrix. The thermal and mechanical properties of PVA-g-GO/PVA nanocompistes were also studied.
