Abstract:
A preparation method of polyporous scaffold for repairing tissue and organ includes the following steps: firstly, selecting pore-forming agent, dissolving degradable polymer in solvent, then adding pore-forming agent in solution, placing the mixture in mould, clamping mould, drying, demoulding, drying in vacuum drying oven, soaking the dried product in deionized water or acid aqueous solution, and then vacuum drying so as to obtain the invented polyporous scaffold. By regulating grain size of pore-forming agent and concentration of solution, the said invention can obtain the scaffold with intercommunication between pores and different porosity.
