A new flow cell system we have designed for thin film samples is used to measure the streaming potential between two parallel films of a polyurethane (PU)/polyvinyl chloride (PVC) blend, and the ζ-potential of PU/PVC blend dope-coated nylon fabrics is then estimated. Furthermore, we propose a novel streaming potential method to directly measure coated films on the inside of the cell lid and the cell body. The ζ-potential of PVC-rich (hydrophobic) surfaces has a lower value than that of PU-rich (hydrophilic) surfaces.
一种新的流动细胞系统我们有专为薄膜样品是用来测量流潜力在两个平行薄膜的聚氨酯(PU)/聚氯乙烯(PVC)混合,ζ-potential PU / PVC共混dope-coated尼龙面料进行了测算。此外,我们提出了一种新颖的方法来直接测量流潜力上涂上一层的电影里面的细胞盖和细胞的身体。PVC-rich的ζ-potential表面的疏水性)(有价值较低(比PU-rich亲水性)表面。
