| 摘 要： | 采用剪切黏度法对聚氯乙烯(PVC)/聚偏氟乙烯(PVDF)/聚甲基丙烯酸甲酯(PMMA)体系的相容性进行研究,结果表明,该体系为部分相容体系,在此基础上采用稀溶液黏度法对各共混配比的相容性进行预测.对相容性较好的PVC/PVDF/PMMA共混体系由相转化法制备共混膜,并用扫描电镜对共混膜的形态结构进行了观察.对共混膜的...

| Abstract: | The miscibility of PVC/PVDF/PMMA blending system was investigated by means of shearing viscosity.It was demonstrated that blended solution possessed partial miscibility.Then the dilute solution viscometry was used to determine the miscibility of all sorts of polymer blending ratio.PVC/PVDF/PMMA blend membranes were prepared by phase inversion.The micro-structure of blend membranes was analyzed by SEM and the water permeability,mechanical character and contact angle of blend membranes were measured too.The r... |
