A Novel Conductive, Redox Polymer for Battery and Applications

这个小型企业创新研究(SBIR)第二阶段项目是在分析和表面化学的一般领域，以及在电化学和材料化学的子领域。这项活动的目标是开发由取代吡咯合成的导电聚合物，作为充电电池电极和其他应用的材料。在前面的第一阶段研究中，EIC实验室，Inc.证明了可以合成一种聚吡咯(PP)共聚物，该共聚物含有可通过PP主链电化学访问的苯醌侧基。该公司进一步证明，在水溶液中，这些苯醌基团的存在增强了导电聚合物的电化学容量。在目前的第二阶段活动中，前一阶段的工作正在扩大和扩大范围。目前的研究任务包括：(1)开发和优化取代吡咯单体的新合成路线；(2)新型PP共聚物的合成与评价，包括掺杂电势和掺杂水平的优化，取代PP膜电导率的表征，对苯二酚侧链的pH依赖性的研究，以及对苯二酚电催化动力学的考察；以及(3)衍生聚吡咯在电池技术、传感器电极、催化和电导氧化还原聚合物中的应用研究。从这项研究中衍生出的新材料可能会有广泛的、技术上重要的应用。

This Small Business Innovation Research (SBIR) Phase II project is in the general area of analytical and surface chemistry and in the subfields of electrochemistry and materials chemistry. The goal of this activity is to develop electrically conducting polymers synthesized from substituted pyrroles as materials for rechargeable battery electrodes and other applications. In the preceding Phase I research, EIC Laboratories, Inc. demonstrated that a polypyrrole (PP) copolymer could be synthesized that contained quinone pendant groups which are electrochemically accessible via the PP backbone. The company further demonstrated that in aqueous electrolytes, the presence of these quinone moieties enhanced the electrochemical capacity of the conducting polymer. In the present Phase II activity, the previous Phase I work is being extended and broadened in scope. Research tasks for the current effort include: (1) the development and optimization of new synthetic routes to substituted pyrrole monomers; (2) the synthesis and evaluation of new PP copolymers including optimization of the doping potential and doping level, characterization of the electronic conductivity of substituted PP films, investigation of the pH dependence of the pendant quinone moieties, and examination of the kinetics of electrocatalysis by these quinones; and (3) investigation of applications of derivatized polypyrroles in battery technology, sensor electrodes, catalysis, and conductivity redox polymers. The new materials derived from this research could enjoy broad, technologically important applications.
