▎ 摘　　要

NOVELTY - A graphene-doped tin oxide-modified composite nano-fiber air-sensitive material comprises 35-50 pts. wt. pyrrole monomer, 15-24 pts. wt. polyvinyl alcohol, 13-25 pts. wt. zinc, 40-55 pts. wt. N,N-dimethyl formamide, 5-10 pts. wt. p-toluenesulfonic acid, 70-95 pts. wt. ferric chloride, 5-11 pts. wt. copper nitrate, deionized water, absolute ethanol, 3-8 pts. wt. stannic chloride, 0.4-1 pts. wt. graphite oxide, 20-35 pts. wt. ammonia water and 2-5 pts. wt. hydrazine hydrate. USE - Graphene-doped tin oxide-modified composite nano-fiber air-sensitive material for use in poisonous and harmful gas detection and monitoring. ADVANTAGE - The graphene-doped tin oxide-modified composite nano-fiber air-sensitive material has increased specific surface area. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing a graphene-doped tin oxide-modified composite nano-fiber air-sensitive material.
