Abstract: A paper forming mold, comprising a roller (1). A number of through micropores are formed on a wall of the roller (1), and one or more patterns and characters of a normal watermark, a white watermark, a windowed security thread, and a paper marker are carved on the wall of the roller (1). The paper forming mold has a high reproducibility for an original watermark design draft, improves consistency, clarity, three-dimensionality, detail refinement and richness of the watermark in paper, and thus enhances the anti-counterfeiting function of the watermarked paper; the service life of the paper forming mold is prolonged; and the automation level of paper forming mold manufacturing is improved, and the labor intensity is greatly reduced.

Abstract: A substrate having a superhydrophobic surface and methods of manufacturing the same and uses thereof. The substrate comprises a frame of a first material of interconnected structures exhibiting cavities having the shape of inverted pyramids; and a second material comprising hydrophobic structures filling the cavities, wherein the sidewalls of the inverted pyramids form an angle ? of 105°<?<135° against the surface. The hydrophobic structures, such as nanoparticles, provide excellent water repellency, whereas the structures formed by a mechanically durable substrate material, typically comprising microstructures, act as armor to resist abrasion. The substrates are robust, durable and abrasion resistant and can be used as surfaces in self-cleaning, anti-fouling or heat transfer materials as well as in transparent surfaces, in particular in solar cells.
