ABSTRACT:
The present invention provides an ozone detecting material comprising a polymer prepared by polymerization of at least one monomer selected from the group consisting of 2-, 3-, 4-halogen substituted anilines or aniline substituted with C1-3-alkyl in N-position, and diphenylamine, formed into a thin film coated on a transparent substrate, waveguide, or optical fiber, or additionally comprising a component selected from electro-conductive fine carbon powder, a semiconductive metal oxide, or a semiconductive polymer material, and a method for detecting ozone comprising the steps of contacting this ozone detecting material with an ozone-containing gas and determining the light absorption rate and/or electrical conductivity of the ozone detecting material at that time.
