HYDROPHILIC FILM, PREPARATION METHOD AND APPLICATIONS THEREOF |
摘要 |
The present invention provides a hydrophilic film that causes a liquid to diffuse rapidly in a single direction. The hydrophilic film comprises a substrate having a texture of parallel sunken and raised patterns, and a hydrophilic coat comprising a coat of silicon dioxide particles. The present invention also provides a method for preparing the hydrophilic film. The method comprises: preparing an aqueous dispersion of silicon dioxide particles, wherein the average size of the silicon dioxide particles is 1 to 60 nm, and the concentration of the silicon dioxide particles is 0.05% to 15% by weight; coating the aqueous dispersion of silicon dioxide particles on a substrate, wherein the substrate has a texture of parallel sunken and raised patterns; and drying the substrate coated with the aqueous dispersion of silicon dioxide particles. |
