Preparation method and product of piezoelectric hydrogel |
| abstract |
The preparation method of the piezoelectric hydrogel of the present invention includes the following steps: Step 1: Dissolving the matrix material with both mechanical properties and biocompatibility in an aqueous solution at 90° C. to form solution A; dissolving the piezoelectric material in an aqueous solution at 75° C. Solution B is formed in the dimethyl sulfoxide solution; Step 2: The solutions A and B obtained in Step 1 are quickly mixed and poured into a mold, and then placed in a refrigerator at -20°C for freezing. Electrogel; Step 3: After thawing the piezoelectric hydrogel obtained in Step 2, put it into an ethanol gradient solution for dehydration and removing residual dimethyl sulfoxide to obtain a piezoelectric hydrogel product. The invention can adapt to the mechanical strength of different defect parts, and finally achieves the purpose of repairing the defect parts through the combined action of the physiological microenvironment simulated by the hydrogel and piezoelectric stimulation. The invention also discloses the piezoelectric hydrogel product prepared by the above method. |
