氧化石墨烯(GO)作为石墨烯(G)的衍生物有着与石墨烯相类似的力学性能和导热性能等优异性能,并且其亲水性官能团使其相比于石墨烯来说更容易在水中分散从而更容易与水泥基相结合.大量研究已表明 GO掺入水泥基中不但可以增强水泥基的力学性能和耐久性能还可以增强水泥基的电磁屏蔽性能、导热性能等性能,为多功能型、智能型混凝土的开发提供了可能.以GO 复掺其他功能纤维材料在水泥基中的应用为中心,简述了GO 的性能特点、结构特质从而表明GO 在水泥基材料中应用的广度和范围,并重点综述了 GO 的分散性研究和GO 复掺纤维水泥基的工作性能、水化过程、力学性能、耐久性能、功能性能的研究,并对未来GO 复掺纤维水泥基材料研究的方向进行了展望.
Summaryof research on graphene oxide composite fiber material cement-based composites
Graphene oxide(GO),as a derivative of graphene(G),has excellent mechanical properties and ther-mal conductivity similar to graphene,and its hydrophilic functional groups make it easier to disperse in water and combine with cement-based materials.A large number of studies have shown that adding GO into cement matrix can not only enhance the mechanical properties and durability of cement matrix,but also enhance the e-lectromagnetic shielding properties and thermal conductivity of cement matrix,which provides the possibility for the development of multifunctional and intelligent concrete.Focusing on the application of GO mixed with other functional fiber materials in cement-based materials,this paper briefly describes the performance charac-teristics and structural characteristics of GO,thus indicating the breadth and scope of its application in cement-based materials,emphatically summarizes the research on the dispersion of GO and the working performance,hydration process,mechanical properties,durability and functional properties of GO mixed with fiber cement-based materials,and looks forward to the future research direction of GO mixed with fiber cement-based mate-rials.
