Research Progress on Dispersion Technology and Properties of Graphene Cement-based Composites

石墨烯水泥复合材料不但具有低密度和高比表面积等优点,同时也结合了二维碳纳米材料自身的柔软性和优良的力学、电学性能。由于石墨烯在水中的分散较为困难,易于团聚,导致其对水泥性能的提升作用有限,因此石墨烯的分散问题是优化水泥基材料性能的关键。本文主要阐述了石墨烯在水泥基材料中的分散工艺、对水泥基材料性能的增强,并总结概述了现阶段石墨烯水泥基复合材料在多个领域中的应用研究进展。

Graphene cement composites not only have the advantages of low density and high specific surface area,but also combine the softness of two-dimensional carbon nanomaterials with excellent mechanical and electrical properties.The dispersion of graphene in water is difficult and easy to aggregate,which leads to its limited effect on the performance of cement.Therefore,the dispersion of graphene is the key to optimize the performance of cement-based materials.The dispersion process of graphene in cement-based materials and the enhancement of the properties of cement-based materials were described,and the current research progress on the application of graphene cement-based composites in many fields was summarized.
