聚丙烯作为一种性能优良的通用型热塑性塑料,在各个领域中得到了广泛使用.石墨烯具有优异的力学性能、导电性能和导热性能,是聚合物复合材料的理想填料.综述了石墨烯在聚丙烯中的应用,主要介绍了石墨烯在聚丙烯中的添加方法,包括熔融共混、溶液共混、原位聚合和乳液共混,归纳了这4种方法的优缺点,主要体现为石墨烯在聚丙烯中的分散性;总结了石墨烯对聚丙烯结晶和熔融行为、力学性能和导电性能的影响,具体表现为成核聚丙烯的结晶峰温度的高低以及半结晶时间的长短、刚性的改善效果和导电率的大小.根据石墨烯/聚丙烯复合材料的性能特征,展望了复合材料在未来的发展趋势.

Polypropylene is widely used in various fields as a general-purpose thermoplastic with many excellent properties.Graphene as an ideal filler for polymer composite has excellent mechanical properties,electrical conductivity and thermal conductivity. The application of graphene in polypropylene is reviewed. The addition methods of graphene in polypropylene are introduced,including melt blending,solution blending,in-situ polymerization and emulsion blending. The advantages and disadvantages of these four methods are summarized,which mainly manifests the dispersion of graphene in polypropylene. Th...
