Abstract

The invention belongs to the technical field of sensor materials, and concretely relates to a self-repairing ultra-sensitive conductive electronic skin sensor material and a preparation method thereof. The method comprises the following steps: wrapping the surface of graphene oxide with anthocyanidin, adding the wrapped graphene oxide to an aqueous solution of polyvinyl alcohol (PVA) / glycerin, performing uniform mixing, and coagulating the obtained mixture with a borax solution to prepare self-repairing ultra-sensitive PVA hydrogel. The graphene oxide / anthocyanidin compound makes the PVA hydrogel have an ultra-sensitive performance, so the PVA hydrogel can be used as the self-repairing ultra-sensitive conductive electronic skin sensor material.

Description

technical field [0001] The invention relates to a novel self-repairing electronic skin sensor material, in particular to a self-repairing supersensitive conductive electronic skin sensor material and a preparation method thereof. Background technique [0002] Hydrogel (Hydrogel) introduces a part of hydrophobic groups and hydrophilic residues into water-soluble polymers with a network crosslinked structure, and the hydrophilic residues combine with water molecules to connect the water molecules inside the network, while Cross-linked polymer with hydrophobic residues that swell with water. Hydrogel is a polymer network system, which is soft in nature, can maintain a certain shape, and can absorb a large amount of water. Although there are many kinds of materials for preparing hydrogels, polyvinyl alcohol (PVA) has always been the polymer of choice for preparing hydrogels. This is mainly because PVA hydrogel has the advantages of low toxicity, high water absorption and good ...
