SGER: Equilibrium Absorption Properties of Real Polymer Systems. A Study Using Self-Assembled Monolayers as Model Systems

摘要cts-9872082 a。开发一种简单、快速、具有成本效益的初步筛选方法的新想法将被探索，用于开发改性聚合物的新应用，如气体分离和水相流的废物回收。这种方法将允许测试具有不同侧链结构的大量聚合物的渗透选择性特性。在使用的方法中，不需要合成这些聚合物，允许更快地进行筛选实验，并且比目前的做法显著降低成本。利用表面活性剂的支撑自组装单层（SAMs）作为聚合物膜的模型将被探索。形成sam的表面活性剂与形成膜的聚合物具有相同的侧链，但它们不是单体，不能用于聚合物的合成。由于大量的这些自组装表面活性剂已经存在，因此可以在不需要任何合成努力的情况下形成大量聚合物的模型sam，将筛选侧链所需的时间减少到每个样品的几个小时。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。＊＊＊

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. ***
