聚氯乙烯-聚乙烯醇的相容性及其复合多孔膜的结构与性能OA北大核心CSTPCD
Compatibility of Polyvinyl Chloride-Polyvinyl Alcohol and Structure and Properties of Their Composite Porous Membranes
通过溶液成膜法制备了聚氯乙烯-聚乙烯醇(PVC-PVA)复合多孔膜,从聚合物混合焓及分子之间相互作用的角度探讨了PVC和PVA两者之间的相容性,采用扫描电子显微镜(SEM)、接触角测量仪及平板超滤膜测试仪等分析了复合多孔膜的孔形貌、亲水性、过滤性能及力学性能.研究结果表明,在PVC-PVA复合体系中,大分子之间可形成氢键及偶极相互作用,混合焓随PVA在聚合物中质量分数的增大而呈现先增大后减小的趋势,PVC-PVA总体上为部分相容.与纯PVC膜相比…查看全部>>
