This project takes a systematic approach to designing membranes for selective separation of alcohols such as ethanol and butanol from aqueous mixtures. The membrane morphology is controlled by the well-established principles of block copolymer self-assembly. Examples of morphologies include alternating lamellae of A and B or cylinders of A in a B matrix. The size and geometry of the transporting channels are controlled by varying the molecular weight and composition of the copolymer. The project will enable the quantification of the effect of channel structure on selectivity and throughput.
