NOVELTY - Preparing graphene quantum dot hybrid multi-response self-repairing structural color hydrogel array comprises e.g. (1) using the sacrificial template process, adding polymer monomer A and polymer monomer B to initiator and crosslinking agent, mixing uniformly to obtain a polymer precursor, filling the polymer precursor in the photonic crystal template, carrying light-induced polymerization, and removing the template to obtain a stimuli-responsive structured color hydrogel with three-dimensional periodic arrangement structure; (2) dissolving the graphene quantum dot powder in pure water to prepare a graphene quantum dot solution with a series concentration within range of 0.5-4 mg/mL; and (3) dissolving polymer monomer C and polymer monomer D in graphene quantum dot solution of series concentration obtained in the step (2), adding the borax solution, stirring evenly, dropping the obtained mixed solution on surface of stimuli-responsive structured color hydrogel obtained in step (1). USE - The hydrogel array is useful in information security system with information multiple encryption and step-by-step identification and decryption of mobile phone applets, and useful in optical anti-counterfeiting (All claimed). ADVANTAGE - The hydrogel array: has dynamically adjustable structural color, multiple stimuli responsiveness, fluorescent properties, and self-repairing ability; and can be remotely controlled by absorbing the energy of near-infrared light.
