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. ***

小行星9217526 本提案的目的是进行一个系统的，多技术调查的纳米尺度的结构和电子性能的薄膜来自苯胺，官能化苯胺，苯胺共聚物。 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）技术。 STM和TS提供了材料表面的局部、纳米分辨率的结构和电子信息。 XPS识别聚合物膜的化学状态，而EPR将用于研究聚合物的顺磁性。 该研究将开始与电化学电镀和独立的膜的聚合物衍生自苯胺，羟基苯胺，苯胺-3-氨基苯硼酸。 本研究的主要目标是从根本上了解化学结构对纳米尺度结构和形态的影响和相互作用。 此外，这些材料的化学和物理结构将与所观察到的宏观传导性质相关。 这项研究在一个本科生，少数民族机构服务美洲原住民将允许学生参与当代材料研究处理聚合物合成金属。 ***
