▎ 摘 要
NOVELTY - Porous support has surface functionalized bioactive nanocomposite coatings and 3 dimensional printing porous metal stent. The coating is fibroin-graphene oxide nanocomposite coatings, where graphene oxide concentration is 0-0.6 wt.%. USE - Porous support. ADVANTAGE - The porous support has bactericidal or bacteriostatic effect due to the presence of metal ions, and has good biological activity and coating function.
