Disclosed are a self-induction hydrogel light-transmitting smart glass and a preparation method therefor, which belong to the technical field of polymer materials. The self-induction hydrogel is a multi-response (thermal, electrical, pH) hydrogel, and the self-induction hydrogel is composed of a polymerized monomer, a surfactant, a reinforcing agent, a corresponding initiator, a cross-linking agent, (an accelerator), and a salt solution. The present invention uses the surfactant in the hydrogel as a response unit, which spontaneously forms micelles in a gel network with cations in the salt solution. The particle size of the micelles changes under the action of heat, electricity and pH. The macro performance is a change in the transmittance of the prepared gel. When the hydrogel is in a solution state, same is injected into a laminated glass and then sealed, and after in-situ gelation of same, a self-induction multi-response light-transmitting smart glass can be obtained. Compared with other inventions, the hydrogel prepared in the present invention has the features of high light transmission, multiple responses, and a wide response range (24.5-48°C). |
