Abstract

PS-grafted-titanium oxide (diameter 15 nm, TiO2) and PS-grafted-aluminum hydroxide (diameter 37 nm, Al2O 3·xH2O) nanoparticles were successfully prepared through direct polymerization from immobilized surface initiator that has both phosphoric acid moiety and living radical polymerization moiety. In the case of PS film with non-grafted-TiO2, the films did not show high light transmittance and ultraviolet absorption characteristic owing to the aggregation of nanoparticles. On the other hand, in the case of PS film with PS-grafted-TiO2, the films showed high transmittance in the visible light region accompanying ultraviolet absorption characteristic of TiO 2 due to the fine dispersion of nanoparticles into PS matrix. PS film with PS-grafted-Al2O3·xH2O showed good flame resistance compared with non-grafted-pseudo-boehmite or PS-grafted-boehmite with diameter 240 nm and 110 nm (plate) because of good dispersion in PS matrix and release of structural water during PS degradation.
