Electrophoretic deposition is currently one of the most relevant technological methods for production of electrically conductive materials. In the work, the method of electrophoretic deposition obtained Electrically conductive materials based on carbon fibers (CF) have been obtained for the first time by electro-phoretic deposition using graphene oxide (GO) and silver nanoparticles. The obtained materials exhibit increased electrical conductivity, surface activity, and enhanced physical and mechanical properties. The purpose of the study is development of the methods for producing electrically conductive carbon textile materials by electrophoretic deposition of graphene oxide using galvanic deposition of silver nanoparticles from an electrolyte. Electrophoretic deposition was performed in 1 cm increments and at a constant voltage of 160 V during 20, 40, and 60 sec. Infrared spectroscopy data showed that GO particles are fixed on carbon textile materials. The carbon textile materials (CF/GO/NP Ag/60) thus obtained formed a new structure with several layers of graphene oxide and silver nanoparticles. The CF deposition increases the surface roughness of the hydrocarbon and thus improving the wettability and adhesion. An analysis of the spectra obtained by X-ray photoelectron spectroscopy for CF showed significant changes in the binding energy and the energy of excited photoelectrons. Compared with the initial hydrocarbons, the obtained carbon materials exhibited an increased content of silver and oxygen, whereas carbon to oxygen ratio decreased. The developed technique allowed us to obtain carbon textile materials with high electrical conductivity being 2.5 as much the original CF. Introduction of the silver nanoparticles contributes to filling of the surface cracks in CF. An increase in the share of reduced graphene oxide can significantly increase the surface roughness, electrical conductivity, surface energy and improve the screening properties of carbon textile materials. The effectiveness of screening in the obtained materials is 24.4 % higher than that in the initial CF which expands the potentiality of their application in novel technical textile products of the future.

Conductive Composite

Cellulose/Ag/polyaniline conductive composite with rather excellent electrical conductivity was heterogeneously synthesized in this paper. The UV-Vis analysis indicated that homogeneous nanoAg particles deposited on the surface of cellulose in the form of globe particles. They offered some electrons to polyaniline chains. This behavior resulted to the facts that more polyaniline embedded on cellulose and an integrated electrically conductive network formed. Consequently, the high electrical conductivity of the composite was observed. The value was 3.48 S/cm, which was higher two magnitudes than the electrical conductivity of cellulose/polyaniline composite (2.15×10-2S/cm), and even was higher than the electrical conductivity of pure polyaniline (0.142 S/cm). This paper provided a facile method for the preparation of cellulose/Ag/ polyaniline composite with favorable electrical conductivity.
