摘要：

The maximum pressure difference a supported liquid membrane can resist is related to the membrane maximum pore size and the pore structure, interfacial tension of fluids and contact angle. Critical displacement pressures (P(c)) for Durapore HVHP, Accurel 2E-PP and Celgard 2500 membranes were tested experimentally in different systems. A neck model was established to estimate P(c) of supported liquid membranes considering the departure of membrane pores from a cylindrical capillary. The experimental results were in good agreement with the estimated values.
