A double hydrophobic and amphiphilic block copolymer nanostructured membranes were manufactured by non solvent induced phase inversion (NIPS) technique. The combination of NIPS process and self assembly of block copolymer aids us to produce an isoporous membrane with pores sizes of about 20-30nm.1,2 Here we used PS-b-PEO (amphiphilic) and PS-b-PMMA (double hydrophobic) block copolymer for nanostructured membrane formation. The self assembled structures of polymer membranes were tuned using the mixture of different solvent compositions and polymer concentrations. Pure water was used as a phase inversion medium for the nanostructured membrane formation. SEM, AFM and TEM measurements were employed to characterize the self assembled structure of the membranes.ReferencesKarunakaran, M.;  Qiu, X.; Yu, H.; Nunes, S. P.; Peinemann K.-V.;  J.
