A novel non-electrolytic route using non-equilibrium physicochemical reactions was used to synthesize a silver/carbon nanocomposite. Using the polarization effect of polar molecules, an electrical current was passed in the circuit under the influence of an external high-strength electric field. It allows to exclude any electroconductive additives in the solvent. Simplicity of process allows to extend an ability of surface plasma interaction with polar liquid for synthesis nanomaterials by non-electrolytic technique. (C) 2017 Elsevier B.V. All rights reserved.
