| titleOfInvention | A kind of preparation method of piezoelectric polymer material |
| abstract | The invention discloses a preparation method of piezoelectric polymer material. Mix L-polylactic acid (PLLA) and PHBV (3-hydroxybutyrate and 3-hydroxyvalerate copolymer) materials according to a certain proportion, dissolve in dichloromethane, and slowly add a certain volume of the aforementioned polymer solution to the process. In the stirred polyvinyl alcohol aqueous solution of a certain concentration, at a certain temperature and for a certain time, the polymer microspheres in the polyvinyl alcohol aqueous solution are allowed to stand for precipitation, washed several times, and dried at 50 ° C for 12 hours. The final powder is obtained, and the powder is injected into a metal mold with a specific shape and heated and sintered to obtain a piezoelectric tissue repair scaffold material with a specific shape. Compared with the prior art, the advantages of the present invention are: 1), the obtained polymer material has excellent piezoelectric properties; 2), the obtained polymer material has good processability. |
