【Abstract】 Of all kinds metallic biomaterials, biomedical stainless steels are widely used in clinical field because of their excellent comprehensive properties. In this paper, Aimed at the existing problems at present of biomedical stainless steels after surgery, the preparation methods and the advanced progress of surface modification are introduced in recent years. The main functions of chitosan are summarized, and so did the present investigations of chitosan at home and abroad. On the basis of that, This article focuses on the possibilities and the potential applications of the chitosan as biomedical coating on 316LSS are explored.更多还原
