A wide variety of glass products would greatly benefit from coatings that offer anti-reflective, anti-glare, anti-fog, anti-ice, self-cleaning, and other advanced functions. State-of-the-art coatings do not meet desired performance characteristics or cannot be applied over larger areas in a cost-effective manner. As a direct consequence, new coating solutions and application techniques are urgently needed. Advanced coatings based on nanopatterned surfaces found in nature (e.g. moth eye, lotus leaf, and others) have proven to be very efficient in achieving the abovementioned properties. The combination of large required area (> 300 mm wafers), small feature size, and low cost preclude using projection lithography tools from the semiconductor industry and conventional conveyor or web technology used for large roll to roll film processing. Rolith, Inc. has developed a new concept of continuous-type low cost nanopatterning, which is scalable to large glass surfaces. We report on results of nanopatterning of 1 m x 0.3 m glass plate with sub-300 nm resolution and demonstrate some practical applications of this technology for anti-reflective and superhydrophobic glass surfaces, and ITO-free conductive electrodes.
