近年来, 碳纤维(CF)以其优异的力学性能和导电性能, 被广泛用作复合材料的增强体。CF增强水泥基复合材料的机械性能在很大程度上取决于CF的分散性, 以及CF与水泥基体之间的界面特性。利用氧化石墨烯(GO)来改性CF的表面特性, 提高CF在水泥基中的分散性及CF与水泥基体之间的键合, 从而提高水泥基复合材料的性能。重点综述国内外GO改性CF(GO-CF)水泥基复合材料的应用现状, 并在此基础上, 对GO-CF水泥基复合材料的研究趋势及前景进行展望。
In recent years, carbon fiber (CF) has been widely used as a reinforcement for composite materials due to its excellent mechanical properties and electrical conductivity.The mechanical properties of carbon fiber reinforced cement-based composites depend largely on the dispersibility of CF and the interface characteristics between CF and the cement matrix.Graphene oxide (GO) is used to modify the surface characteristics of CF to improve the dispersion of CF in the cement base and the bonding between CF and the cement matrix, thereby improving the performance of cement-based composites.This article focused on the application status of GO-CF cement-based composites at home and abroad, and on this basis, the research trend and prospects of GO modified CF cement-based composites were prospected.
