SGER: Interface Modification by Chemically Bound Self-Assembling Polymers

摘要CTS-9870881 S.Webber/美国德克萨斯州这项建议的目标是制备、表征和利用基于附着在表面上的嵌段共聚物的新型界面结构。嵌段共聚物的自组装趋势将被发掘。该项目将包括(1)通过阴离子聚合合成各种嵌段共聚物(有些带有荧光标记)；(2)由这些共聚物形成的胶束的制备和表征；(3)将这些胶束附着到各种表面；(4)通过各种加工步骤，如溶剂和/或温度循环，对涂有胶束的表面进行改性；(5)通过一系列技术对表面进行表征；(6)研究干燥表面与各种蒸汽的相互作用以及浸没界面与可溶性探针的相互作用。据推测，除了对这些新结构的内在兴趣外，该项目还可能在化学传感、光学数据存储和药物输送领域带来有价值的进展。首席调查员对所提出的大多数技术都有丰富的经验。所需的大多数设备和仪器要么是PI实验室常规使用的，要么是德克萨斯大学随时可用的。***

ABSTRACT CTS-9870881 S. Webber/U. Texas The goal of this proposal is preparation, characterization and utilization of novel interface structures based on block copolymers attached to surfaces. The self-assembling tendency of block copolymers will be exploited. The project will include (1) synthesis of various block copolymers (some with fluorescent tags) by anionic polymerization; (2) preparation and characterization of micelles formed by these copolymers; (3) attachment of these micelles to various surfaces; (4) modification of the micelle-coated surfaces by various processing steps such as solvent and/or temperature cycling; (5) characterization of the surfaces by an array of techniques; (6) studying the interaction of the dry surfaces with various vapors and of the submerged interfaces with soluble probes. It is surmised that, besides the intrinsic interest in these novel structures, the project may lead to valuable advances in the fields of chemical sensing, optical data storage and drug delivery. The principal investigator has had extensive experience in most of the techniques proposed. Most of the equipment and instrumentation needed is either routinely used in the PI labs or is readily available within the University of Texas. ***
