1 results about "Polyhydroxyethyl Methacrylate" patented technology

The application provides an ultrasonic response piezoelectric ionic hydrogel and application thereof, and the hydrogel is formed by cross-linking and solidification of a precursor solution under ultraviolet irradiation; components of the precursor solution include a photosensitive polymer, an ionic polymer, a photoinitiator and a solvent; the photosensitive polymer includes any one or a combination of at least two of polyether F127 diacrylate, polyhydroxyethyl methacrylate, polyethylene glycol dimethyl acrylate, methacrylated gelatin or methacrylated collagen; and the ionic polymer includes any one or a combination of at least two of epsilon-polylysine, polyethyleneimine hydrochloride, polyallylamine hydrochloride, polyquaternary ammonium salt-10 or cationic guar gum. The application uses ultrasonic waves as an external remote driving signal to non-invasively and painlessly activate the piezoelectric ionic effect of the hydrogel, generate detectable periodic voltage and current signals in the hydrogel, and has excellent treatment effect on acne and infected wound repair.
