一、前言随着近代外科医疗技术的不断提高,对可植入人体的生物材料的需求也在增大,这种应用条件,一方面材料要具有能承担一定功能的力学性质,另一方面也要求植入假体能满足生物相容性的要求。任何人工材料,要同时满足这两方面的要求,存在着相当的困难和复杂性,这正是生物医学材料的研究工作所必须解决的问题。作为生体用碳素材料的研究,是本世纪60年代开始的,当时在人造血管的抗血凝材 I. Introduction With the continuous improvement of modern surgical medical technology, the demand for biomaterials that can be implanted in the human body is also increasing. Under such application conditions, on the one hand, the material needs to possess the mechanical properties capable of assuming certain functions; on the other hand, Requiring implants to meet the biocompatibility requirements. Any artificial material, at the same time to meet these two requirements, there are considerable difficulties and complexities, which is biomedical materials research work must be addressed. As a bio-carbon material research, is the beginning of 60s of this century, when anti-blood clot material in the artificial blood vessels
