文摘

Block copolymer self-assembly based non-solvent induced phase separation is studied. Dependence of asymmetric membrane substructure on casting conditions is tested. Parameters tested include polymer concentration, evaporation time, and solvent ratio. Results provide design guidelines for sponge- and finger-like substructure formation.
