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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Hydrophilic film, preparation method and applications thereof","description":"The present invention provides a hydrophilic film that causes a liquid to diffuse rapidly in a single direction.
