▎ 摘  要

NOVELTY - Composite test material based on graphene oxide comprises graphene oxide-polyacrylic acid composite dispersion as an anion assembly and fluorine-containing polyacrylate resin as cation assembly, where the fluorine-containing polyacrylate resin is prepared by fluorine-containing polyacrylate and isocyanate curingagent and the monomer of the fluorine-containing polyacrylate comprises (methyl) acrylic acid tertiaryamine ester. USE - The test material is useful as a humidity sensor (claimed). ADVANTAGE - The test material maintains an excellent linear relationship; and indicates that the stability and repeatability meet the requirements of testing humidity materials. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparing composite test material comprising immersing cationic assembly fluorine-containing polyacrylate resin body in the graphene oxide-polyacrylic acid composite dispersion liquid, fully immersing, and taking out and drying; and (2) use of test material as a humidity sensor comprising irradiating material using infrared light and obtaining the environmental humidity according to the linear relation of the absorbance-humidity.
