-
摘要: 以壳聚糖季铵盐,壳聚糖为基本原材料,选用戊二醛为交剂剂及固定剂,制备一种物理机械性能较优的抗凝血材料。探讨了戊二醛及肝素钠两者用量对肝素化程度及血液生的影响。Abstract: A new antiocoagulant material with good physico-mechanical properties was prepared by using chitosan quaternary ammonium salt and chitosan as raw materials,glutaraldehyde as crosslinking and fixation agent. The influence of the amounts of the added hepari
