| 摘 要： | 在无化学处理的条件下制备出淀粉/聚乙烯醇(PVA)复合膜, 进行了力学性能、 溶胀度及红外光谱测试, 并通过溶血试验、 动态凝血试验、 血小板消耗试验对复合膜的血液相容性进行了表征。研究结果表明, 通过共混改性把淀粉引入到PVA中, 改善了力学性能和血液相容性。当PVA与淀粉的质量比为4∶1时, 复合膜的抗拉强度为13.73 MPa, 抗拉应变率为43.07%, 性能最佳。

| Abstract: | The starch/polyvinyl alcohol(PVA) composite membranes were prepared through blending PVA with starch without any chemical treatment.The starch/PVA membranes were characterized by the mechanical assay,swelling test and FTIR analysis.The blood-compatibility of the blending films was evaluated by using the hemolysis assay,dynamic coagulation time and platelet consumption.The results show that the mechanical properties and blood-compatibility of composite membranes are improved as blending starch into PVA.When ... |
