| 摘 要： | 采用湿法相转化制膜技术制备PU/PVC共混膜、PU/PVC/SiO2共混膜。PVC可以改变铸膜液体系在凝固浴中的分相速度,提高成膜性及改善膜的微孔结构,在此共混物中加入SiO2可以显著改善膜的微孔结构,并提高PU共混膜的水通量,可用于超滤。用扫描电镜对膜的结构形态进行了观察。

| Abstract: | It prepared Polyurethane/Poly(vinyl chloride)(PU/PVC) blend membrane and Polyurethane/Poly(vinyl chloride)/Silicon dioxide(PU/PVC/SiO_2) composites by means of Loeb-Sourirajan phase transition method.By adding PVC,the phase separating rate of casting solution in coagulating bath can be changed with the addition of PVC,and the membrane-forming ability and the cellular structure of membrane are also improved;the cellular structure of the composites membrane is improved with the addition of the SiO_2,and the pure water flux is enhanced,so the PU composites membrane can be used for ultrafiltration membrane.It observed the microstructure and morphology of membrane through SEM. |
