▎ 摘　　要

NOVELTY - A multi-component supramolecular hydrogel contains component containing strong hydrogen bond i.e. carbon oxide nanotubes, graphene oxide, carboxylated ferroferric oxide nanoparticles, carboxylated silver nanoparticles, carboxylated quantum dot, polyacrylic acid, polypropylene glycol, polyvinyl alcohol, polyurethane, polyamide, and/or poly(sodium-p-styrenesulfonate), component containing weak hydrogen bond i.e. small molecular compound or high molecular compound containing primary amine, sec.-amine, or tert.-amine, and water. USE - Multi-component supramolecular hydrogel for sensors, actuators, controlled drug release, self-healing materials, mobile smart adhesives, and artificial joints. ADVANTAGE - Multi-component supramolecular hydrogel is very sensitive to external stimuli, and has good magnetic conductivity and self-healing capabilities. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of multi-component supramolecular hydrogel which involves mixing component containing strong hydrogen bond and water to obtain aqueous solution of component containing strong hydrogen bond, adding component containing weak hydrogen bond, uniformly mixing to obtain suspension, and standing.
