由于特殊用途的制约,医疗行业在材料的抗菌性、耐腐蚀性、无毒害方面都有相当高的要求。研究表明双亲性聚氨酯材料具有良好的生物兼容性、血液兼容性,不吸收人体蛋白质,其性能又可根据要求方便地调整,可用于制作人造血管、人造皮肤、软骨和心脏瓣膜等医 Due to special-purpose constraints, the medical industry has very high demands on the antibacterial, corrosion-resistant and non-toxic materials. Studies have shown that amphiphilic polyurethane material has good biocompatibility, blood compatibility, does not absorb the human protein, its performance can be easily adjusted according to requirements, can be used for the production of artificial blood vessels, artificial skin, cartilage and heart valves and other medical
