Table 1 Comparison of theoretical relationship with experimental results for various porous membrane/gating liquid/transport liquid combinations.

The parameters are measured at room temperature (25°C). The unit of γA, γB, γAB, ΔEI, and ΔEII is mN/m. The unit of θA and θB is degrees (°). The case number is arranged on the basis of the order of solid materials.
