  • Patent number: 8314039
    Abstract: The invention relates to surfaces with hydrophilic properties and a method for producing such surfaces. Surfaces are provided with hydrophilic properties by applying a coating containing hydrophilic silicic acid by means of the inventive method. Said surfaces can be textile or polymer surfaces, metallic or wooden surfaces. The silicic acid can be permanently connected to the polymer surface or be in the form of a non-fixed coating. The inventive hydrophilic silicic acid is applied in a very simple manner by applying a suspension containing silicic acid particles in a solvent on the corresponding surface, whereupon the solvent is removed or the silicic acid particles are fixed to the surface by means of a carrier. Condensing devices of dehumidifiers, foams or sponges are examples of surfaces that can be provided with the inventive hydrophilic surfaces.
