Characteristics and self-cleaning effect of the transparent super-hydrophobic film having nanofibers array structures

An efficient way to prepare hydrophobic antireflective SiO2 film by sol–gel method

“…By replacing the groups and controlling the surface morphology, the antireflective coating can achieve high transmittance and good hydrophobicity simultaneously in theory. Over the past decade, many efforts have been made to improve the transmittance or hydrophobicity, but few people could give consideration to both high transmittance and good hydrophobicity [9][10][11][12] . In our work, we presented a simple efficient approach to obtain an antireflective and hydrophobic surface by dip-coating a single-layer sol-gel film on glass and introducing PFDS to realize high transmittance and good hydrophobicity at the same time.…”

Enhancement of Corrosion Resistance of Aluminum 7075 Surface through Oil Impregnation for Subsea Application

“…The dimensions of the nanoporous structure like pore diameter, interpore distance, and thickness of the nanoporous oxide layer can be controlled by changing the type and concentration of the acid electrolyte solution, anodic voltage, anodizing time, and temperature [7][8][9][10][11][12][13]. The anodizing time affects the pore depth, and the anodic voltage and the temperature of the electrolyte solution influence the pore diameter and the interpore distance [14]. S.-K. Hwang et al [13] experimentally showed that the anodizing time determines the pore depth.…”

Controlled transparency and wettability of large-area nanoporous anodized alumina on glass

“…Surface wetting properties such as superhydrophilicity and superhydrophobicity have attracted significant attention for their potential applications based on their desirable functions, such as anti-fogging [1], enhanced heat transfer [2], self-cleaning [3], water drag reduction [4], and anti-icing/deicing effects [5,6]. A superhydrophilic or superhydrophobic surface can be produced by modifying the surface energy and creating micro/nano-textures on the surface [7][8][9][10][11][12].…”

“…Recently, in order to expand their potential applications to optical fields such as building windows, solar cell panels, vehicle glass, and electronic devices, superhydrophilic/superhydrophobic transparent surfaces have been developed based on plasma etching [13], sol-gel processes [14], a nanolithographic technique [15], nanoparticle assembly [16], and nanotemplating [17]. Since wetting characteristics and transparency are competitive properties from the viewpoint of surface roughness (i.e., the wetting properties increase with roughness, whereas the transparency decreases) [3], the roughness should be precisely tuned to satisfy both characteristics at wavelengths shorter than visible light (at least <400 nm). However, most of these methods still suffer from the need for time-consuming processes, specialized expensive equipment, and elevated temperatures.…”
