项目摘要

ABSTRACT CTS-9872082 A. Couzis/CUNY A novel idea to develop a simple, fast and cost effective, preliminary screening method will be explored for the development of modified polymers in new applications, such a gas separations and waste remorse from aqueous streams. This method would allow for the testing of the permeation selectivity properties of a large number of polymers with various side chain structures. In the approach used, the synthesis of these polymers will not be required, allowing running of screening experiments faster and with significantly reduced cost over the current practices. To do the use of supported self-assembled monolayers (SAMs) of surfactants as models of the polymer membranes will be explored. The surfactant forming the SAMs will have the same side chain as the membrane-forming polymer, but they are not monomeric and cannot be used in the polymer's synthesis. Because a very large number of these self-assembling surfactants already exists, model SAMs for a large number of polymers can be formed without the need for any synthetic effort reducing the time required to screen side chains to just a few hours for each sample. This sample-screening tool would then become an important part in the development efforts for improved polymer membrane materials required by industry. ***

摘要CTS-9872082 A. Couzis/纽约市立大学一个新的想法，开发一个简单，快速和成本效益，初步筛选方法将探索改性聚合物在新的应用，如气体分离和废水处理的发展。该方法将允许测试具有各种侧链结构的大量聚合物的渗透选择性性质。在所使用的方法中，将不需要合成这些聚合物，从而允许更快地运行筛选实验并且与当前实践相比具有显著降低的成本。要做的使用支持的自组装单分子膜（SAM）的表面活性剂作为模型的聚合物膜将进行探索。形成SAM的表面活性剂将具有与成膜聚合物相同的侧链，但它们不是单体的并且不能用于聚合物的合成。由于已经存在大量的这些自组装表面活性剂，因此可以形成大量聚合物的模型SAM，而不需要任何合成工作，从而将筛选每个样品的侧链所需的时间减少到仅几个小时。这种样品筛选工具将成为工业所需的改进聚合物膜材料开发工作的重要组成部分。 ***
