Preparation and Properties of the Polystyrene/Alumina Nanocomposites

Abstract:

Silane coupling agent KH-570 was applied to modify the surface capability of the alumina (Al₂O₃). The modified Al₂O₃ were dispersed in styrene. The in-situ polymerization was used to prepare the polystyrene/alumina (PS/Al₂O₃) composites, in which azodiisobutyronitrile (AIBN) was used as initiator. FTIR, DSC and TG were applied to characterize the prepared composites. The solvent resistance, thermal resistance of the composites and the average molecular weight of PS in PS/Al₂O₃ nanocomposites were studied. The experimental results demonstrated that the solvent resistance of PS/Al₂O₃ nanocomposites was improved by the adding of Al₂O₃ nanoparticles. The thermal resistance of the composites increased with the increasing of the Al₂O₃ content. Meanwhile, the molecular weight of PS in the composites increased with the increasing of the Al₂O₃ content.
