  • Preparation method for water-loss-resistant ionic conductive gelatin hydrogel
    Patent number: 12404375
    Abstract: Disclosed in the present invention is a preparation method for a water-loss-resistant ionic conductive gelatin hydrogel, including: adding a gelatin into deionized water for soaking and swelling, and then placing the gelatin in a water bath and carrying out magnetic stirring to obtain a gelatin solution; adding sodium pyrrolidone carboxylate into the gelatin solution to carry out treatment to obtain a gelatin-sodium pyrrolidone carboxylate mixed solution; and cooling the gelatin-sodium pyrrolidone carboxylate mixed solution at a certain temperature to obtain a gelatin-sodium pyrrolidone carboxylate hydrogel.
    Type: Grant
    Filed: March 10, 2025
    Date of Patent: September 2, 2025
    Assignee: ZHEJIANG UNIVERSITY
