NOVELTY - A cerium loaded-functionalized material is obtained by adding graphene into absorbable macromolecule polymer and loading with cerium as rare-earth element, reinforcing and toughening, obtaining biodegradable carrier material, hot-pressure forming obtained material, providing porous hydroxyapatite ceramic layer with pure magnesium or magnesium alloy wire, or sheet, and chemically impregnating composite form of rare-earth element using electrophoresis-micro-arc oxidation method. USE - Cerium loaded-functionalized material is used for orthopedic instrument. ADVANTAGE - The cerium loaded-functionalized material is efficiently prepared. DETAILED DESCRIPTION - A cerium loaded-functionalized material is obtained by adding graphene into absorbable macromolecule polymer and loading with cerium as rare-earth element, reinforcing and toughening, obtaining biodegradable carrier material, hot-pressure forming obtained material, performing slow release process of cerium as rare-earth-element having antibacterial anti-inflammatory effect, providing porous hydroxyapatite ceramic layer with pure magnesium or magnesium alloy wire, or sheet, and chemically impregnating composite form of rare-earth element using electrophoresis-micro-arc oxidation method. The content of biodegradable carrier material is 10-75 volume%. The porous ceramic layer has pore size of 1-50 mu m and thickness of 1-100 mu m. The amount of graphene is 0.01-5 volume%. An INDEPENDENT CLAIM is included for preparation of cerium loaded-functionalized material.
