Phenomenological mannequin of synthesis of few-layer graphene (FLG) by the selfpropagating high-temperature synthesis (SHS) methodology from biopolymers: Fullerenes, Nanotubes and Carbon Nanostructures: Vol 0, No 0



A phenomenological mannequin for the synthesis of few-layer graphene (FLG) nanosheets by the strategy of self-propagating high-temperature synthesis (SHS) from starch, lignin, and different biopolymers is taken into account. We recommended that polysaccharides, particularly starch, could possibly be an appropriate supply of native cycles for the SHS course of. The carbonization of biopolymers underneath the circumstances of the SHS course of was chosen as the fundamental methodology of synthesis. Chemical reactions, underneath the circumstances of the SHS course of, proceed in accordance with a selected mechanism of nonisothermal branched-chain processes, that are characterised by the joint motion of two basically totally different process-accelerating components – avalanche replica of lively intermediate particles and self-heating. It’s proven that the proposed mannequin can clarify the manufacturing of few-layer graphene nanosheets with linear dimensions of tens of microns and a thickness of a number of graphene layers.
