聚乙烯醇-海藻酸钙的制备

摘要聚乙烯醇海藻酸钙具有弹性好、柔韧性大和含水率高等优点。以含水率为指标,通过正交试验设计,对聚乙烯醇海藻酸钙聚合物制备的条件进行优化,找出最佳的制备条件:ω(戊二醛)为0 85%、m(PVA)∶m(NaAlg)为10∶1、ω(CaCl2)为2 0%。通过聚乙烯醇、海藻酸钙形成的膜材料以及聚乙烯酸海藻酸钙膜材料的对比试验,结果表明,聚乙烯醇海藻钙膜材料的含水率、拉伸强度和扯断伸长率都是最高的。

Abstract： PVA-alginate-Ca is of good elasticity,better flexibility and high water content.Based on water content,the preparation of PVA-alginate-Ca was optimized by experiment.The optimum preparation conditions were selected: the glutaraldehyde concentration was 0.85%,the ratio of PVA to NaAlg was 10∶1 and CaCl_2 concentration was 2.0%.Comparison of characteristics among PVA,alginate-Ca and PVA-alginate-Ca shows that the water content,tensile strength and elasticity of PVA-alginate-Ca are the highest.
