    摘要: A photocatalytic functional film has a structure of a substrate, a barrier layer and a photocatalytic layer stacked one on another. The barrier layer is a SiO2 film, the photocatalyst layer comprises an amorphous TiO2 film, and particles of visible light responsive photocatalytic material formed on the surface of the amorphous TiO2 film. A method for producing a photocatalytic functional film includes: adding an alcohol solvent and an acid to a silicate precursor to obtain a SiO2 sol by dehydration and de-alcoholization reaction; applying and drying the SiO2 sol on a substrate to form a barrier layer; adding an alcohol solvent and an acid to a titanium precursor to obtain a TiO2 amorphous sol by dehydration and de-alcoholization reaction; and applying and drying a composition formed by mixing particles of visible light responsive photocatalyst material with the TiO2 amorphous sol on the barrier layer, to form a photocatalyst layer.

    摘要: Provided is a sound absorption sheet comprising an improved micro-resonance layer formed by means of a porous substrate and printing. The method for manufacturing a sound absorption sheet comprises the steps of: preparing a porous substrate; forming a micro-resonance layer by printing on the upper part of the porous substrate; and drying the micro-resonance layer.
