Abstract

This work presents a comparison between electrochemical (Echem), plasma glow, and arc discharge polymerizations of pyrrole doped with iodine to correlate the energy of synthesis, chemical structure, and electrical conductivity of the polymers. Plasma glow discharges were used in the gas phase, electrochemistry in liquid, and arc discharges in a hybrid gas–liquid combination. Polypyrroles had structure and conductivity that varied with the synthesis parameters; Echem produced polymers with high carbonization and without the C≡N triple bonds resulting from the other syntheses. Conductivity divided the polymers in two: those synthesized in liquid were in the 0.01–1.0 S/m range, and those synthesized in gas were in the 10–9–10–7 S/m range, with differences of up to eight orders of magnitude due to the dopants and electrolytes.

聚吡咯的电聚合,电化学、辉光和电弧放电之间的比较
本研究对掺杂碘的吡咯的电化学聚合(Echem)、等离子辉光聚合和电弧放电聚合进行了比较,以便对聚合物的合成能量、化学结构和导电性能进行相关分析。等离子辉光放电用于气相,电化学用于液相,电弧放电用于气液混合。聚吡咯的结构和电导率随合成参数的不同而变化;Echem 合成的聚合物碳化程度高,没有其他合成方法产生的 C≡N 三键。导电性将聚合物一分为二:在液体中合成的聚合物在 0.01-1.0 S/m 的范围内,而在气体中合成的聚合物在 10-9-10-7 S/m 的范围内,由于掺杂剂和电解质的不同,两者之间的差异高达 8 个数量级。
