Abstract

Electroactive composite coatings (CCs) are prepared on the basis of 3,6-di(3-aminophenylene)amino-2,5-dichloro-1,4-benzoquinone (DAPADCB) and its polymerization product poly-DAPADCB. We use two types of carbon substrates: (1) with a smooth surface, which are represented by glassy carbon (GC) and Graflex commercial graphite foil (GF), and (2) with a rough surface, which is represented by activated graphite foil (AGF). For the substrates of the first type, coatings are fabricated by oxidative polymerization on the substrate surface, while, for the second type, CCs are prepared by spreading a suspension of poly-DAPADCB in formic acid, in which the DAPADCB monomer is polymerized in advance, on the substrate surface. We study effects related to incorporation of single-wall carbon nanotubes and graphene oxide. The fabricated coatings exhibit high specific electrochemical capacitance (up to 2800 F/g) and extended cycling ranges (up to 2 V).

碳基质形态对聚（3,6-二（3-氨基亚苯基）氨基-2,5-二氯-1,4-苯醌）电活性复合涂层电化学性能的影响

摘要

基于3,6-二（3-氨基亚苯基）氨基-2,5-二氯-1,4-苯醌（DAPADCB）及其聚合产物poly-DAPADCB制备电活性复合涂料（CCs）。我们使用两种类型的碳基材：（1）表面光滑，以玻璃碳（GC）和Graflex商业石墨箔（GF）为代表；（2）表面粗糙，以活性石墨箔为代表（AGF）。对于第一类基材，通过氧化聚合在基材表面上制备涂层，而对于第二类基材，通过将聚DAPADCB的悬浮液铺展在甲酸中来制备CC，其中DAPADCB单体已预先聚合，在基材表面上。我们研究与掺入单壁碳纳米管和氧化石墨烯有关的影响。
