Penetration of low‐temperature plasma polymer forming species through a microporous polycarbonate membrane was indicated by advancing contact angle measurement and scanning electron microscopoy of the membrane surface. No penetration of plasma polymer forming species was found in nylon and poly(vinylidene fluoride) membranes. This is attributed to the tortuous pore shapes of the nylon and poly‐(vinylidene fluoride) membranes compared to the straight cylindrical pore shape of the polycarbonate membrane.
