Abstract
A process for the deposition of nano/microparticles, including at least graphene sheets on a support, comprises the following steps: oxidizing at least the graphene sheets; suspending the nano/microparticles in at least one solution comprising at least water as solvent; spraying, by hydrodynamic instability, each suspension over the substrate; heating the substrate, during each spraying, so as to promote the complete evaporation of the solvent from each part of each suspension sprayed over the substrate at a temperature less than or equal to one and a half times the boiling point of each solution and less than or equal to 200° C.; annealing the deposit after the spraying(s) at a temperature sufficient to deoxidize at least the oxidized graphene present in the deposit and greater than the temperature of the substrate during the deposition step.
