Described is a micro-structured paper or paper-like material having a self-cleaning and/or non-adhesive effect whereby the paper or paper-like material is hydrophobic across the entire cross-section of the material and which is micro-structured in such a way that the surface is provided with elevations and depressions whereby the distance between the elevations ranges from 0.04 to 100 microns and the height of the elevations ranges from 0.04 to 100 microns, and whereby the paper or paper-like material is characterized in that it contains particles having the size of 0.04 to 50 microns that are bound to the paper or paper-like material by means of a binder, and whereby the paper or paper-like material is hydrophobic across the entire cross section of the material, as well as a method for the production thereof.
A micro-structured paper or paper-like material having a self-cleaning and/or non-adhesive effect whereby said paper or paper-like material is hydrophobic across the entire cross-section of the material and which is micro-structured in such a way that the surface is provided with elevations and depressions whereby the distance between the elevations ranges from 0.04 to 100 microns and the height of the elevations ranges from 0.04 to 100 microns, and whereby said paper or paper-like material is characterized in that it contains particles having the size of 0.04 to 50 microns that are bound to said paper or paper-like material by means of a binder, and whereby said paper or paper-like material is hydrophobic across the entire cross-section of the material.
A method to manufacture micro-structured paper or paper-like material that is water-repellant across the entire cross section of the material and having a self-cleaning and/or non-adhesive effect, and which is provided with elevations and depressions whereby the distance between the elevations ranges from 0.04 to 100 microns and the height of the elevations ranges from 0.04 to 100 microns as well, characterized in that particles of a size of 0.04 to 50 microns are added to the fibers of the paper or paper-like material and whereby said particles are fixed to the fibers by means of a binder together with the use of a water-repelling agent in the scope of a wet-laying method.
