摘要
氧化石墨烯(GO)因其出色的性能在改善水泥基材料微观结构、力学性能上均有很好的应用前景。然而,GO的增强效果很大程度上取决于其在水泥基体中的分散性。总结了近年来GO在水泥基材料中的研究成果,重点综述了GO的分散方式、分散机理以及相应的力学性能改善机理;对比了不同GO分散方式的优缺点,分析了GO分散前后对水泥基材料微观结构和力学性能的影响;提出了目前研究存在的问题,并对未来研究趋势进行展望;旨在为后续GO在水泥基材料中的稳定应用提供参考,以促进制备高效功能化的GO水泥基复合增强材料。
Graphene oxide(GO)has promising applications in improving the microstructure and mechanical properties of cementitious materials due to its excellent properties.However,the enhancement effect of GO is largely dependent on its dispersion in the cement matrix.This paper summarizes the research results of GO in cementitious materials in recent years,focusing on the review of GO dispersion methods,dispersion mechanisms,and the corresponding mechanical property improvement mechanisms,comparing the advantages and disadvantages of different GO dispersion methods,and analyzing the effects on the microstructure and mechanical properties of cementitious materials before and after GO dispersion.The problems of the current research are pointed out,and an outlook on future research trends is provided,aiming to provide a basis for subsequent GO in cementitious materials for stable applications,in order to promote the preparation of highly functionalized GO cementitious composite reinforced materials.
