Cathodic doping of thin-layered composites. Formed by electroactive polymers and rubbed single-walled carbon nanotubes

A simple method of electrostatic rubbing is developed for the application of single-walled carbon nanotubes (SWNT) to solid substrates. The method is applicable both to conducting materials (for example, glassy carbon) and insulators (for example, Teflon). The surface development of the obtained coatings is comparable to the bodies of multi-walled carbon nanotubes, which are grown on the TiN substrates. The possibility of cathodic doping of electron-conducting polybithiophene polymer and poly-o-phenylenediamine redox polymer on the substrates with SWNT is shown. The presence of nanotubes accelerates anodic synthesis of test polymers and improves the reversibility of their cathodic doping, the electrode surface development being the main factor.
