Preparation method of high-tensile-stress self-repairing compound

The invention provides a preparation method of a novel high-tensile-stress self-repairing compound. The above material is prepared from graphene oxide and polyvinyl alcohol by adopting a method of circulating freezing and thawing and then drying. The hydrogen bond sites of the compound are increased by utilizing rich oxygen-containing group characteristics of graphene oxide, and a dynamic reversible hydrogen bond network is formed, so that the compound has self-repairing performance, and meanwhile, the mechanical properties of the compound are also enhanced. The material is simple in preparation process, free of pollution and easy for industrial production. 本发明提供了一种新型高拉伸应力自修复复合物的制备方法。该材料由氧化石墨烯与聚乙烯醇，采用先循环冷冻解冻，后烘干的方法制得。该复合物利用氧化石墨烯的丰富的含氧基团特性增加复合物的氢键位点，形成动态可逆的氢键网络使复合物具有自修复性能，同时还增强了复合物的力学性能。该材料制备工艺简单、无污染、易于工业化生产。
