The invention relates to a degradable piezoelectric film for bone repair and a preparation method thereof, comprising the following steps: (1) adding a cermet dispersion into a polymer solution, stirring uniformly to obtain a mixed solution; wherein the polymer is a polymer solution (3-hydroxybutyrate) or a derivative thereof; (2) taking the mixed solution for electrospinning to form a film, and drying to obtain a degradable piezoelectric film for bone repair. The invention uses degradable polymer poly(3-hydroxybutyrate) or its derivatives as the base material, and at the same time, the film is doped with cermet, so that the hydrophilic property is improved while the piezoelectric performance of the film is improved, and the degradation is stable. , which is conducive to lasting stimulation of cell proliferation and differentiation, and does not require secondary surgery to remove. |
