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.

该小型企业创新研究 (SBIR) 第二阶段项目属于分析化学和表面化学的一般领域以及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可充电电池电极和其他应用的材料。 在之前的第一阶段研究中，EIC Laboratories, Inc. 证明可以合成包含醌侧基的聚吡咯 (PP) 共聚物，这些醌侧基可通过 PP 主链进行电化学连接。 该公司进一步证明，在水性电解质中，这些醌部分的存在增强了导电聚合物的电化学能力。 在目前的第二阶段活动中，之前的第一阶段工作正在得到扩展和范围扩大。 目前的研究任务包括：（1）取代吡咯单体新合成路线的开发和优化； (2)新型PP共聚物的合成和评价，包括掺杂电位和掺杂水平的优化、取代PP薄膜的电子电导率表征、醌侧基的pH依赖性研究以及这些醌的电催化动力学研究； (3) 衍生化聚吡咯在电池技术、传感器电极、催化和导电氧化还原聚合物中的应用研究。 这项研究产生的新材料可以享受广泛的、具有重要技术意义的应用。
