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.

在美国和其他工业化国家，膜分离技术的研究正在迅速发展。虽然近年来高分子材料取得了重大进展，但高分子材料在工业生产中的应用仍然存在差距，在设计用于分离技术的膜用高分子共混物方面还有很多工作要做。在这一关键领域的研究很少，而这一提议提供了一个急需的倡议。具体来说，本文概述了一些初步的工作，旨在系统地研究聚合物膜的物理和化学性质与膜的渗透性和分离效率之间的关系。
