▎ 摘　　要

NOVELTY - A absorbing 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 - Absorbing material is used for orthopedic instrument. ADVANTAGE - The absorbing material is efficiently prepared. DETAILED DESCRIPTION - A absorbing material is obtained by adding graphene into absorbable macromolecule polymer and loading with copper ion, reinforcing and toughening, obtaining biodegradable carrier material, hot-pressure forming obtained material, promoting regeneration of copper ion, providing porous hydroxyapatite ceramic layer with pure magnesium or magnesium alloy wire, or sheet, and chemically impregnating composite form of copper ion 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.
