▎ 摘　　要

NOVELTY - Composition comprises graphene, conductive polymer, cellulose-based resin, solvent, ester-based resin and curing agent. USE - The composition is useful in chemical substance detection sensor through resistivity changes depending on hydrogen ion index (all claimed). ADVANTAGE - The composition can be applied to substrate. The sensor detects hazardous chemicals with high sensitivity through electrode containing graphene. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: producing composition, comprising (a) mixing graphene, a conductive polymer, a cellulose-based resin, and a solvent primarily, (b) adding and mixing an ester-based resin secondarily, and (c) adding and mixing a curing agent; and producing chemical detection sensor, comprising applying the composition prepared by the above method to a substrate to a thickness of 0.1-1 mm.
