Аннотация:The optically transparent materials based on organic-inorganic terpolymers of poly(titanium oxide) in organic copolymers of hydroxyethyl methacrylate and acrylonitrile and modified by F-content agent were demonstrated UV-induced reversible wettability. The poly(titanium oxide) inside the material had a structure close to anatase and uniformly distributed over the surface of the sample as it was determined by X-ray phase analysis and electron microscopy. The single-electron transition Ti4++ e– ⇆ Ti3+ occurred in the samples under UV-irradiation accompanied by triple bondTi-O bond breaking and change of surface hydrophilicity with change of contact wetting angle from 77° to 5°. The transformation in the nature of the initial surface from hydrophilic to hydrophobic was provided by its treatment with poly-1,1,5-trihydroperfluoroamyl acrylate latex, the contact wetting angle increased up to 97°. The modified surface exhibited the ability to reversibly change the wettability during UV-irradiation. Light irradiation of surfaces coated with palmitic acid demonstrated the photocatalytic activity of the material in the decomposition of organic pollutants and their propensity to self-cleaning.
