Abstract

Una membrana porosa la cual tiene una membrana de pared constituida de un polímero hidrofóbico y un polímero hidrofílico. Cuando la membrana de la pared es dividida igualmente en tres en la dirección del espesor, es decir, una región (a) que incluye una superficie de la pared (A), una región (c) que incluye la otra superficie de la pared (C), y una región (b) entre la región (a) y la región (c), entonces el contenido de polímero hidrofóbico en la región (a), (Ca) es mayor que el contenido de polímero hidrofílico en la región (cc), y el diámetro de poro promedio de la superficie de la pared (C) es más grande el diámetro de poro promedio de la superficie de la pared (A).
