▎ 摘　　要

NOVELTY - Gas-sensitive composite nanofilm is produced by dispersing graphene oxide in organic solvent to obtain graphene oxide dispersion solution; dripping the dispersion solution onto ultra purified water on Langmuir-Blodgett film trough, allowing dispersion solution to spread out on water surface, compressing the spread dispersion solution in a film-forming mold to form thin nanofilm, transferring formed nanofilm to a gas-sensing device, performing reduction treatment, and depositing conductive polymer layer on the nanofilm. USE - Method of producing gas-sensitive composite nanofilm.
