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

Summary

A phenomenological mannequin for the synthesis of few-layer graphene (FLG) nanosheets by the tactic of self-propagating high-temperature synthesis (SHS) from starch, lignin, and different biopolymers is taken into account. We recommended that polysaccharides, particularly starch, may very well be a suitable supply of native cycles for the SHS course of. The carbonization of biopolymers beneath the circumstances of the SHS course of was chosen as the fundamental methodology of synthesis. Chemical reactions, beneath the circumstances of the SHS course of, proceed in response to a particular mechanism of nonisothermal branched-chain processes, that are characterised by the joint motion of two essentially totally different process-accelerating components – avalanche copy of energetic 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.
