The present invention relates to a phase-separated particle preparation method for a porous framework used in the prostheses of tissue and organs. First is to select the pore-forming agent and dissolve the degradable polymer in the dissolvent, then put the pore-forming agent into the polymer solution. After mixed even, the mixture is put into the mould and to be quenched and then knocked out of the mould and dried. Then the freeze-dried preparation is dipped into deionized water or weak acid aqueous solution and vacuum dried again thereafter. Thus the porous framework of the present invention is prepared. The framework material prepared using the method of the present invention is high in porosity, good in biological compatibility and biologically degradable. |
