▎ 摘　　要

NOVELTY - Characteristic response material comprises 60-70 wt.% matrix material, 5-15 wt.% modified anthocyanin and 2-10 wt.% titanium dioxide (TiO2) porous microsphere. USE - The material is useful for monitoring and detecting hydrogen sulfide gas leakage, and petrochemical industry, natural gas chemical industry and coal chemical industry field. ADVANTAGE - The material solves the problem that the detection hydrogen sulfide the gas in the existing technology depends on precise instrument closed detection or manual operation detection, has wide monitoring coverage range, high sensitivity, visual visual and convenient construction and other technical effects, and realizes the integrated package protection of the connecting part and the hydrogen sulfide of the gas corrosion leakage. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the response material, comprising (i) placing the matrix material, TiO2 microspheres and modified anthocyanin in an ethanol-water solvent with a volume ratio of 5:5 and mixing to obtain a composite material, and (ii) pouring the mixed composite material into a prefabricated mold.
