23 Jul Method for preparing polycaprolactone-keratin composite porous scaffolds
Abstract
The invention relates to a method for preparing polycaprolactone-keratin composite porous scaffolds. The method includes the steps that polycaprolactone is dissolved into solvent and stirred to be dissolved, and then a polycaprolactone solution is obtained; keratin is dissolved into solvent and stirred to be dissolved, and then a keratin solution is obtained; the polycaprolactone solution and the keratin solution are mixed according to the mass ratio of 95:5 to 5:95 and stirred to be evenly mixed, a polycaprolactone/keratin solution is obtained, the polycaprolactone/keratin solution is poured into a mold and frozen, and a frozen solid is obtained; the frozen solid is freeze-dried, and a polycaprolactone-keratin composite porous scaffold material can be obtained. The polycaprolactone-keratin composite porous scaffold material is prepared through the freeze-drying technology. The porous scaffold material has the advantages of being high in porosity, good in communication performance and biocompatibility, degradable and the like and can be used in the fields of tissue engineering scaffolds of skin, bones and the like, cell culture, medicine transportation and the like.
