Preparation method of repairable graphene oxide material based on hydrogen-bond interaction

The invention discloses a preparation method of a repairable graphene oxide material based on hydrogen-bond interaction, and belongs to the field of polymer self-repairing materials and anticorrosivecoatings, and the preparation method comprises the following steps: reacting 1, 2-bis (2-aminoethoxy) ethane with 1, 1 '-thiocarbonyl diimidazole during preparation to obtain an ether-thiourea polymerwith a hydrogen-bond thiourea structure; the ether-thiourea polymer is grafted to the surface of graphene oxide prepared by an optimized Hummers method through an amidation reaction, and the repairable graphene oxide material based on the hydrogen bond action is obtained. According to the repairable graphene oxide material based on the hydrogen bond interaction, the problem that the mechanical property and the self-healing effect of a hydrogen bond self-healing material are generally exclusive is solved. The hydrogen bond type thiourea structure endows the material with better self-healing ability, and the mechanical
