Abstract

Abstract:

In order to explore the preparation process of graphene?reinforced composite materials with industrial development prospects, graphene/polypropylene composite materials were prepared using the melt blending method, and the graphene reinforcement mechanism was analyzed through experimental and computational analysis. The results indicate that through melt blending, graphene can be uniformly dispersed in the matrix. The tensile strength of the composite material with a graphene mass fraction of 0.5% is 50.3 MPa. When the mass fraction of graphene is 4.0%, the elastic modulus and tensile strength of the composites are increase by 77.1% and 22.5%, respectively, compared to the polypropylene matrix alone. The uniform dispersion of graphene and the interaction between graphene and the polypropylene matrix enable effective stress transfer at the graphene/polypropylene interface.

摘要：

为了探索具有工业化发展前景的石墨烯增强复合材料制备工艺，采用熔融共混法制备了石墨烯/聚丙烯复合材料，并通过实验与计算分析了石墨烯的增强机制。结果表明，通过熔融共混，石墨烯可在基体中均匀分散；当石墨烯质量分数为0.5%时，复合材料的拉伸强度为50.3 MPa；当石墨烯质量分数为4.0%时，复合材料的弹性模量和拉伸强度比聚丙烯基体分别增加了77.1%和22.5%；石墨烯的均匀分散及石墨烯与聚丙烯基体之间存在的相互作用使石墨烯/聚丙烯界面可实现有效的应力传递。
