摘要
介绍了近年来纳米二氧化硅改性聚丙烯复合材料的研究进展,综述了纳米二氧化硅粒子表面处理和添加增容剂改性的主要方法,阐述了纳米粒子与聚合物相容性的提高对复合材料各项性能的改善作用,并讨论了不同纳米二氧化硅颗粒结构对复合材料性能的影响,最后展望了其在改善聚合物渗透性、阻燃性、导电性等方面的发展前景。
With abundant hydroxyl groups on the surface, nano-silica （nano-Si02 with organic polymers containing functional groups. It could improve the ） was easy to react compatibility with polypropylene （PP） matrix and make nano-SiO2 dispersed more uniformly. Recent advances in PP/ nano-SiO2 composites were introduced. The modified methods including surface treatment of nano- SiO2 particles and adding compatibilizer were reviewed. The impact of nano-SiO2 particle structure on the permeability, flame retardancy, electrical conductivity of matrix polymer was also dis- cussed.
