A Method Based on Surface Force Pore Flow Model for Determination of Pore Size and Pore Size Distribution on the Surface of Filtration Membrane

综述了一种建立在表面作用力孔流通模型基础上计算高分子多孔滤过膜孔径大小及分布的方法。

A method based on the surface force pore flow model to characterize the pore size and pore size distribution of polymer porous filtration membranes was reviewed. The method concerned the interfacial interaction force parameters between the probing molecules and the membrane and friction force parameters, and the effect of concentration polarization and measuring pressure. The rejections of experimental value coincided with the calculated value, thus it could give accurate pore size and pore size distribution of filtration membranes.
