Summary
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 urged that polysaccharides, specifically starch, may very well be an appropriate supply of native cycles for the SHS course of. The carbonization of biopolymers below the situations of the SHS course of was chosen as the essential methodology of synthesis. Chemical reactions, below the situations of the SHS course of, proceed in accordance with a particular mechanism of nonisothermal branched-chain processes, that are characterised by the joint motion of two basically totally different process-accelerating elements – 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.
