The article is dedicated to the study of self-organization processes of conductive layer of polyaniline
nanoparticles in heterocoagulation on polyamide fiber. It is shown that the particle size distribution of
polyaniline dispersion obtained by the oxidative condensation of aniline is normal with a maximum
of 150 nm. It is found out that the resistance of the multilayer fibrous material with a polyaniline coating
obtained layer-by-layer depends on the number of layers and the type of the surfactants. The process
of heterocoagulation of polyaniline particles on the polyamide fiber is described by the quasi-chemical
reaction model. It has been shown that in these conditions, the structures with a limited lifetime and with
following self-organization emerge.
