摘要

Phase inversion precipitation of a polysulfone and polysulfone-poly( ethylene oxide) block copolymer solution yields a membrane with an organized surface structure. The poly ( ethylene oxide) block of the polysulfone-poly ( ethylene oxide) block copolymer segregates to the surface of the membrane. Measurement of the H-1 T-1 rho of the component materials, X-ray photoelectron spectroscopy, and differential scanning calorimetry reveal the organized surface structure of the membrane.
