The invention relates generally to optically high transparency and high haze structures and, more particularly, to plastic, e.g., polymer, and glass structures having a sub-wavelength texture formed on a surface thereof, which is effective to impart the optical properties of high transparency and high haze to the structures. The texture is in a grass-like or needle-like form. Additionally, the optically high transparency and high haze structures may include a transparent conductor. Furthermore, the glass structures may exhibit a self-cleaning function.

A method for applying a coating to a surface includes the step of providing a reaction mixture comprising a silicon alkoxide and an alcohol. A reaction limiting amount of water is added. The silicon alkoxides and water are allowed to react to form silica precursor particles during an initial reaction period. A coating precursor composition is prepared by adding an acid soluble in the alcohol to the reaction mixture during a second reaction period after the initial reaction period. The precursor silica particles grow to form silica nanofeatures having a major dimension that is larger than a major dimension of the silica precursor particles. The coating precursor composition is applied to a surface, and the alcohol and water are allowed to evaporate and the silica nanofeatures to adhere to the surface and form a nanostructured layer on the surface. A coating precursor composition and a coated article are also disclosed.
