Abstract：
 A mineralized porous silk protein/high-molecular material composition with high biocompatibility and biodegradability for repairing bone is prepared through preparing the aqueous solution of deglued silk protein, dropping the Ca ions contained solution in it while stirring, slowly dropping PO4 ions contained solution, regulating pH value, stirring, laying aside, centrifugal separation and washing several times, vacuum drying, grinding, and mixing with the biocompatible high-molecular material chosen from polylactic acid, copolymer of lactic acid and hydroxy acetic acid, sodium alginate, etc.
