23 Jul Preparation method of nanocomposite hydrogel with high intensity, high elasticity, electric conductivity and temperature control reversible adhesiveness
Abstract
The invention relates to a preparation method of nanocomposite hydrogel with high intensity, high elasticity, electric conductivity and temperature-controlled reversible adhesiveness. Raw materials include dopamine, aspartic acid, Laponite XLG, NIPAm and the like. The preparation method comprises the following steps of synthesis of dopamine modified PDAEA (polyasparamide); 2, preparation of PDAEA/PNIPAm nanocomposite hydrogel. The preparation method has the advantages that through pyrocatechol structure of dopamine, gel has good biologic adhesiveness; inorganic clay is used as a physical cross-linking point, so that the gel has excellent mechanical performance; the thermosensitivity of PNIPAm can be used for realizing the temperature control reversible adhesiveness of the gel; the gel alsohas excellent electrical conductivity. The gel preparation is simple; compared with the traditional hydrogel, the nanocomposite hydrogel has performance such as excellent mechanical performance, temperature control reversible adhesiveness and electrical conductivity; application prospects are realized in the fields of wound repair, medicine release, tissue engineering, wearable electronic equipment and the like.
