The invention provides a method for preparing nanometer TiO2 sol hybrid coatings. The method is characterized by comprising the steps of: uniformly mixing titanium alkoxide, isopropyl tri(dioctylpyrophosphate) titanate and absolute ethyl alcohol at room temperature, dropwise adding a mixed solution of the absolute ethyl alcohol, deionized water and inorganic acid, stirring for reaction, dripping a silane coupling agent, and continuously stirring for reaction to obtain a transparent and stable TiO2 sol; in addition, slowly dripping the mixed solution of the absolute ethyl alcohol, the deionized water and the inorganic acid after uniformly mixing KH560 with the absolute ethyl alcohol at room temperature, stirring for reaction, then dripping an organic silicon precursor to the TiO2 sol, and stirring for reaction at room temperature so as to obtain the transparent nanometer TiO2 sol hybrid coatings; and forming films by adopting a spin-coating method, a Czochralski method, a spraying method ...
