▎ 摘　　要

NOVELTY - Preparation of tin sulfide nanoparticles/graphene-polyimide based carbon gas gel composite material, involves preparing graphene-polyimide based carbon gas gel, dissolving tin salt and sulfur source in the organic solvent to obtain tin salt solution, reacting graphene-polyimide based carbon gas gel with the iron-tin salt solution, washing and drying using ethanol and deionized water to obtain tin sulfide nanoparticles/graphene-polyimide based carbon gas gel composite material. USE - Preparation of tin sulfide nanoparticles/graphene-polyimide based carbon gas gel composite material used during manufacture of highly sensitive biosensor, lithium ion battery (claimed) and other energy devices. ADVANTAGE - The tin sulfide nanoparticles/graphene-polyimide based carbon gas gel composite material is featured with small size and uniform distribution, high porosity, high specific surface area, improved physical and chemical properties and good stability.
