生物医用材料是用来对生命体进行诊断、治疗、修复或替换其病损组织、器官或增进其功能的材料。
生物医用高分子材料是生物医用材料的一种,也是近几年发展迅速的一个分支。生物医用高分子材料包括天然高分子材料与合成生物高分子材料两种类型。天然生物聚合物是自然存在于生物体中的原料,如:透明质酸、明胶、壳聚糖、海藻酸等,大部分天然高分子材料更易被生物系统接受,具有较好的生物适应性,可以加速伤口愈合。但天然生物材料也存在一定的缺陷,主要有免疫原性、结构复杂性和较差的生物力学特性等。合成生物聚合物具有更好的多功能性、可加工性和可控的降解性。常见的合成生物聚合物有聚硅氧烷、聚丙烯酸脂、聚乳酸等。聚合物的改性是生物医用材料发展的重要手段,在改性条件下可以制备出生物相容性更好,功能性更好的材料。
