| titleOfInvention | Preparation method of dual-response self-repairing hydrogel |
| abstract | The invention belongs to the technical field of high polymer materials, and relates to a dual-response self-repairing hydrogel and a preparation method thereof. P-nitrobenzaldehyde is reduced to obtain P-aminobenzaldehyde, the P-aminobenzaldehyde is subjected to diazo coupling reaction to prepare 4- ((4-hydroxyphenyl) diazenyl) benzaldehyde), then, 4- ((4-formylphenyl) diazenyl) phenyl methacrylate is prepared through acylation reaction, and the phenyl benzaldehyde and polyethylene glycol methyl ether methacrylate are subjected to free radical copolymerization to prepare the water-soluble gel factor P (Azo-co-EGMA) containing azobenzene and aldehyde group. Copolymerizing N-isopropylacrylamide and methyl acrylate to obtain poly (N-isopropylacrylamide-co-methyl acrylate), and hydrolyzing the poly (N-isopropylacrylamide-co-acrylhydrazide) in hydrazine hydrate to obtain poly (N-isopropylacrylamide-co-acrylhydrazide) serving as a second gel factor. And (3) forming reversible acylhydrazone bonds by the two gel factors through hydrazide groups and aldehyde groups to form the dual-response self-repairing hydrogel through crosslinking. |
