无机纳米填料改性聚丙烯的研究进展

Research Progress on Polypropylene Modified through Inorganic Nanometer-filler

综述了聚丙烯/无机纳米复合材料的制备、填料表面处理、物理力学性能。可用大分子相容剂或官能化聚丙烯,改善PP纳米材料的分散性、界面黏结和力学性能。研究表明:少量无机纳米粒子可增强增韧PP。

The recent research progress of the preparation, the surface treatment of filler and the mechanical properties of polypropylenelinorganic nanocomposites were reviewed. The dispersibility, interfacial bonding and mechanical properties of polypropylene nanocomposites were improved by adding compatibilizers with high molecular weight polymeric or functionalizing polypropylene. The results show that PP can be reinforced and toughened by adding few amounts of inorganic nanometer-filler.
