| titleOfInvention | A kind of stress active tissue engineering scaffold material and preparation method thereof |
| abstract | The invention relates to a stress active tissue engineering scaffold material composed of polyvinylidene fluoride nanofibers, silk fibroin and polyvinyl alcohol and a preparation method thereof, and belongs to the field of biomedical materials. The mass ratio of silk fibroin to polyvinyl alcohol is 1/9 to 1/1, the mass ratio of polyvinylidene fluoride to polyvinyl alcohol is 1/99 to 5/95, and the preparation method adopts the suspension of polyvinylidene fluoride nanofibers , silk fibroin solution or silk fibroin powder dispersion is mixed with polyvinyl alcohol solution to obtain a uniform and stable mixed suspension, which is formed by casting mold, freeze-solidified, demoulded, freeze-dried to obtain sponge, and then undergo gas-phase esterification. The tissue engineering scaffold material has uniform and stable microstructure and good biocompatibility, provides matrix conditions for biological tissue growth, and imparts piezoelectric stress response characteristics to the material after being subjected to external force. |
