Abstract

PmAP and PmAP/WO3 composite are synthesized by chemical oxidation polymerization process. Synthesized materials are investigated by UV Visible, SEM and cyclic-voltagram (CV) techniques. SEM study of as prepared materials is indicated formation of different sized crystals (small and aggregated). In UV Visible spectra analyses, both transitioned (i.e., π-π* transition and charge transfer of polaron band) are observed. Tauc expression is used to estimate optical band gap. Estimated optical band gap is to be 3.09 eV. Oxidation-reduction potential profile is detected in cyclic voltammetry (CV) analyses of PmAP and PmAP/WO3 composite.

PmAP/WO3复合材料电化学性能研究
采用化学氧化聚合法制备了PmAP和PmAP/WO3复合材料。采用紫外可见、扫描电镜和循环电压技术对合成材料进行了表征。对制备的材料进行了扫描电镜研究,发现形成了不同大小的晶体(小的和聚集的)。在紫外可见光谱分析中,观察到π-π*跃迁和极化子带的电荷转移。采用tac表达式估计光学带隙。估计光学带隙为3.09 eV。循环伏安法(CV)分析了PmAP和PmAP/WO3复合材料的氧化还原电位分布。
