N2 - This work investigates the impact of the volume ratio of the aqueous and organic phases in reverse microemulsions on the hydrodynamic diameter and electrokinetic potential of gold nanoparticles obtained using such systems. Nonionic biodegradable ethoxylated surfactant Ecosurf SA4 was used as stabilizer. It has been determined that the destruction of micromulsions occurs under the influence of an electric field, accompanied by the separation of the aqueous phase, without coagulation of the nanoparticles. The influence of water on the electrophoretic concentration process was investigated. Different methods for its removal from the organosol were compared. Thermal treatment of pre-dehydrated and concentrated organosols resulted in porous coatings 4–8 μm thick with a metal content of approximately 90 % by mass and an extremely low surface resistivity of less than 100 nOhm per square.
