本研究结合了环境工程、化学工程和聚合物化学等学科，旨在探索新的膜材料，并最终开发高性能、超低污染的膜材料。合成并表征了几种新的聚合物配方。为了测试它们的水渗透性、对天然有机物（NOM）的截留性以及对商用纳滤膜的污染，将两种材料铸入带有聚砜支撑层的薄膜复合膜中。最终的目标是生产一种纳滤膜，它可以像商用膜一样有效地去除NOM，但不易污染或更容易清洗。包括表格，数字。

This research combines the disciplines of environmental engineering, chemical engineering, and polymer chemistry in order to explore new membrane materials and ultimately to develop high performance, ultra-low fouling membrane materials. Several new polymer formulations have been synthesized and characterized. Two have been cast into thin-film composite membranes with a polysulfone support layer in order to test their water permeation, rejection of natural organic matter (NOM) and fouling against a commercial nanofiltration membrane. The ultimate goal is to produce a nanofiltration membrane that can reject NOM as effectively as commercially available membranes but with either less tendency for fouling or easier cleaning.
