We suggest a failure-free method of porous membranes characterization that gives the researcher the opportunity to compare and characterize properties of any porous membrane. This proposal is supported by an investigation of eight membranes made of different organic and inorganic materials, with nine different perfluorinated compounds. It was found that aromatic compounds, perfluorobenzene, and perfluorotoluene, used in the current study show properties different from other perfluorinated aliphatics. They demonstrate extreme deviation from the general sequence indicating the existence of π-π-interaction on the pore wall. The divergence of the flow for cyclic compounds from ideal e.g., linear compounds can be an indication of the pore dimension.
我们提出了一种无故障的多孔膜表征方法，使研究人员有机会比较和表征任何多孔膜的特性。本提议得到了对由不同有机和无机材料制成的八层膜以及九种不同全氟化合物的研究的支持。研究发现，本研究中使用的芳香族化合物、全氟苯和全氟甲苯表现出与其他全氟脂肪族不同的特性。它们显示出与一般序列的极大偏差，表明孔壁上存在π-π相互作用。环状化合物的流动与理想情况（例如线性化合物）的差异可能表明孔的尺寸。
