Abstract

The invention relates to antimicrobial petaloid or schistic Ag/Cu/HAP composite nano-powder and a preparation method thereof. Ag<+> and Cu<2+> which have the strongest antimicrobial resistance are blended into HAP by a coprecipitation hydrolysis method, thus preparing petaloid crystals. The preparation method provided by the invention is simple in operation, uniform and total in doping. The nano-powder, as a raw material, is used for making a composite material with macromolecular substances. The composite material makes an implant which has strong antimicrobial resistance and enduring and wide antimicrobial spectrum. The doping ions, as ions of a transitional element, is composite with the macromolecular substances with strong chemical cohesion; besides, the petaloid crystal shape of the nano-powder is beneficial for attachment and propagation of cells, thereby the nano-powder has good biocompatibility.
