While most of the present medical implants are nonbiodegradable,biodegradable materials are thought to replace many nonbiodegradable ones in the future,which is dependent on development of the corresponding core techniques of biomaterials[1-4].Much progress has been made in the field of biodegradable materials during the last decade[5-7].
