Abstract The paper investigates the possibility of electrodeposition of composite coatings based on polypyrrole with non-functionalized carbon nanotubes or finely dispersed graphite particles from aqueous solutions of pyrrole with contained suspensions of the corresponding carbon materials stabilized by sodium dodecyl sulfate. The carbon particles/nanotubes suspension added to the electrolyte has been shown to significantly accelerate the electropolymerization of pyrrole and make for the formation of porous composites with an extended surface. Varying the suspension concentration it is possible to prepare composites in various polymer/carbon filler ratios. FTIR and Raman studies show that the chemical structure of the polymer depends on the nature of the doping anion, but not on the carbon particles and nanotubes incorporated in the polymer structure. Doping of the polymer with SDS leads to a relatively low electrochemical activity of the composites, which nevertheless increases significantly under cyclic polarization in sulfuric acid solution (0−700 mV vs. Ag/AgCl) due to saturation of the structure with movable bisulfate ions. The as-formed structure exhibits high stability of its electrochemical parameters.

碳纳米管和细分散石墨颗粒对聚吡咯电沉积的影响

摘要 本文研究了基于聚吡咯与非官能化碳纳米管或来自吡咯水溶液的精细分散石墨颗粒的复合涂层的可能性，其中包含由十二烷基硫酸钠稳定的相应碳材料的悬浮液。添加到电解质中的碳颗粒/纳米管悬浮液已被证明可以显着加速吡咯的电聚合，并有助于形成具有扩展表面的多孔复合材料。改变悬浮液浓度，可以制备不同聚合物/碳填料比例的复合材料。FTIR 和拉曼研究表明聚合物的化学结构取决于掺杂阴离子的性质，但不是在聚合物结构中结合的碳颗粒和纳米管上。用 SDS 掺杂聚合物会导致复合材料的电化学活性相对较低，但由于结构被可移动的硫酸氢根离子饱和，因此在硫酸溶液（0-700 mV vs. Ag/AgCl）的循环极化下会显着增加。所形成的结构表现出其电化学参数的高稳定性。
