Abstract

Translucent and superhydrophobic glass surface was fabricated by a NH4F-assisted in-situ growth and post-modification process. Vertical and interconnected layered double hydroxide (LDH) nanosheets were built on the glass surface to enhance surface roughness, and then modified with stearic acid (SA) to reduce the surface energy. The water contact angle (WCA) and water sliding angle (WSA) of the prepared glass was 167° and 2°, respectively, exhibiting the excellent water-repellency and self-cleaning ability. The transparency of the prepared glass was measured by UV–Vis spectrophotometer, and the transmittance in visible region was ranged from 68% to 77.8%. The prepared glass possessed outstanding ability to withstand physical and chemical damage, such as sandpaper abrasion, tape-peeling and acid/base immersion. In addition, the superhydrophobic glass had good environmental adaptability, which can resist UV irradiation and acid raindrop impact. Consequently, the obtained translucent and superhydrophobic glass can be applied in various fields, such as self-cleaning traffic indicators, wind screens, self-cleaning windows and dust-free solar panels.
