Modification of Polyblend Membranes for Separation Processes

膜分离技术的研究在美国和其他工业化国家发展迅速。尽管近年来在聚合物材料方面取得了重大进展，但聚合物在工业过程中的应用仍存在差距，在设计用于分离技术的膜的聚合物共混物方面仍有许多工作要做。在这一关键领域的研究工作很少，而这项提议提供了一个亟需的倡议。具体地说，这项建议概述了一些初步工作，旨在系统地研究聚合物膜的物理和化学性质与其渗透性和分离效率之间的关系。

Research on membrane-based separation technology is growing rapidly in the U.S. and in the other industrialized nations. While significant advances in polymeric materials have been made recently, there is still a gap in application of polymers in industrial processes, and there is much that needs to be done in designing polymer blends for membranes for use in separation tehcnology. There have been very few research efforts in this critical area, and this proposal offers a much-needed initiative. Specifically, this proposal outlines some preliminary work designed to investigate systematically the relation between the physical and chemical properties of polymeric membranes and their permeability and separation efficiency of those membranes.
