Abstract <p>The possibilities of plasma-electrolyte treatment technology and equipment for obtaining electrolyte suspensions with graphene particles by exfoliation of graphite electrodes were studied. The regularities of graphite exfoliation in the anode-cathode processes of plasma-electrolytic treatment were established. It was found that the electrical modes of the technological alternating current source allow producing the electrolyte suspensions with graphene particles with varying degrees of defectiveness through the plasma-chemical exfoliation of graphite: from multilayer graphene particles (the cathode pulse mode) to graphene oxide particles with varying degrees of functionalization (the anode and intermediate modes). It has been established that plasma-electrolytic exposure of highly textured pyrolytic graphite, unlike polygranular graphite, causes the electrode to swell more than tenfold. It is shown that plasma-electrolytic treatment of synthetic graphites is highly effective for obtaining electrolyte suspensions with graphene particles.</p>
