RUI: Experimental Studies of Polymer Films Derived from Aniline

[9217526] Porter本提案的目的是对苯胺、功能化苯胺和苯胺共聚物衍生的纳米级结构和电子特性薄膜进行系统的、多技术的研究。该研究将利用扫描隧道显微镜（STM）、隧道光谱（TS）、x射线光电子能谱（XPS）和电子顺磁共振（EPR）等技术。STM和TS提供材料表面的局部、纳米级的结构和电子信息。XPS鉴定聚合物薄膜的化学状态，而EPR将用于研究聚合物的顺磁性。该研究将从电化学镀膜和由苯胺、羟基苯胺和苯胺-3-氨基苯基硼酸衍生的聚合物的独立薄膜开始。本研究的主要目标是获得对化学结构对纳米尺度结构和形态的影响和相互作用的基本理解。此外，化学和物理结构将与观察到的这些材料的宏观导电性能相关。这项研究在一个为土著美国人服务的本科少数民族机构进行，将允许学生参与处理聚合合成金属的当代材料研究。＊＊＊

9217526 Porter The objective of this proposal is to carry out a systematic, multitechnique investigation of the nanometer-scale structural and electronic properties films derived from aniline, functionalized aniline, and aniline copolymers. The study will utilize the techniques of scanning tunneling microscopy (STM), tunneling spectroscopy (TS), x-ray photoelectron spectroscopy (XPS) and electron paramagnetic resonance (EPR). STM and TS provide local, nanometer-resolved structural and electronic information on the material's surface. XPS identifies the chemical state of the polymer films, whereas EPR will be used to investigate the paramagnetic properties of the polymers. The study will begin with the electrochemically plated and free standing films of polymers derived from aniline, hydroxyaniline, and aniline-3- aminophenylboronic acid. The primary goal of this research will be to gain a fundamental understanding of the influence and interplay that the chemical structure has on the nanometer-scale structure and morphology. In addition both the chemical and physical structures will be correlated to the observed macroscopic conduction properties of these materials. This research in an undergraduate, minority institution serving Native Americans will allow the students to participate in contemporary materials research dealing with polymeric synthetic metals. ***
