多孔β-磷酸三钙/壳聚糖/聚乙烯醇复合水凝胶的制备与性能OA北大核心CSCDCSTPCD
Preparation and Properties of Porous β-Tricalcium Phosphate/Chitosan/Polyvinyl Alcohol Composite Hydrogel
以NaCl为致孔剂,采用溶盐致孔法制备了多孔β-磷酸三钙/壳聚糖/聚乙烯醇(β-TCP/CS/PVA)复合水凝胶材料.通过对比其含水率、溶胀比、拉伸强度、X射线衍射谱图、SEM和热重分析曲线,探讨了在相同环境下壳聚糖与β-磷酸三钙(β-TCP)的不同用量对聚乙烯醇(PVA)的结晶度以及对材料性能的影响.此复合材料含水率为70％ ～ 76％.当壳聚糖与β-TCP的质量比为2∶8时,复合材料的拉伸强度为0.56 MPa,断裂伸长率达到370％,其较好…查看全部>>
Porous β-tricalcium phosphate/chitosan/polyvinyl alcohol (β-TCP/CS/PVA) composite hydrogel was prepared successfully by the freezing-thawing method using NaCl as porogen. The effects of different mass ratio of CS to β-TCP on the crystallinity of PVA and the performance of target β-TCP/CS/PVA composite hydrogel has been studied. The products were characterized by means of XRD, SEM, TG-DTA and their water uptake, swelling ratio, and tensile strength were also …查看全部>>
