▎ 摘  要

NOVELTY - Preparation of tough, stretchable, compressible, self-repairing polymer/graphene oxide nanocomposite hydrogel, involves carrying out in-situ free radical polymerization of acrylamide and acryloyloxyethyltrimethylammonium chloride as comonomers, and graphene oxide nanoparticles. USE - Preparation of tough, stretchable, compressible, self-repairing polymer/graphene oxide nanocomposite hydrogel used for filters of heavy metals, solvents, oils, and gasoline, liquid absorption materials, gas adsorption medium, water purification medium, and electrodes of electrochemical device (all claimed). ADVANTAGE - The method enables simple and convenient preparation of tough, stretchable, compressible, self-repairing polymer/graphene oxide nanocomposite hydrogel having excellent fatigue resistance, high self-repair rate (greater than 92% of tensile strength, greater than 99% of tensile strain, and greater than 93% of toughness), with strong practicability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for nanocomposite hydrogel having a Young's modulus of 1.1 MPa and a toughness of 9.3 MJ/m3.
