Abstract TiN reinforced PS nanocomposites were prepared by melt extrusion method, in which the nano TiN was pretreated by γ-methacryloxypropyl trimethoxy silane (MAPTMS) and macromolecular random copolymer St/AN/MAPTMS, and then blended with polystyrene (PS). The effects of modifiers type on the melt rheological properties, thermal performance and dispersion of nanoparticles of nano TiN reinforced compo-sites were studied. The experimental results discovered that the glass transition temperature, thermal decomposition temperature and uniform dispersion stability of particles of nano TiN reinforced PS composites treated with macromolecular modifier were higher than those of MAPTMS. It indicated that the macromolecular modifier had strongest interfacial bonding effect for TiN reinforced PS nanocomposites. Affected by the interfacial bonding effect between nano TiN and PS, the increase of storage modulus and complex viscosity of the TiN reinforced PS system modified with macromolecular modifier were more obvious.

Key words： nano TiN macromolecular modifier surface modification rheological property interfacial bonding
