| titleOfInvention | Preparation method of intelligent response type hydrogel with interpenetrating network structure |
| abstract | The invention discloses a preparation method of an intelligent response type hydrogel with an interpenetrating network structure, belonging to the technical field of functional materials and high polymer materials. According to the invention, polyacrylamide and sodium alginate modified by phenylboronic acid are taken as high-molecular components of hydrogel, amino-carboxyl condensation reaction is firstly used for synthesizing sodium alginate modified by phenylboronic acid, then acrylamide pre-polymerization liquid and sodium alginate modified by phenylboronic acid are dissolved in deionized water, and polymerization is carried out under heating condition through free radical polymerization reaction, so as to obtain the intelligent response type hydrogel with original interpenetrating network structure. In addition, the intelligent response type hydrogel treated by the polyvalent cation, the alkalinity and the polyvalent cation-alkalinity are respectively prepared based on the coordination complexation of the alginic acid group and the polyvalent cation, the reversible combination of the phenylboronic acid group and the diol structure under the alkaline condition and the combination of the two. The invention realizes the compatibility of high tensile property and multiple functions of the hydrogel, and is beneficial to expanding the application range of the hydrogel. |
