Preparation of sponge-like porous SiO₂antireflective coatings with excellent environment-resistance by an acid-catalysed sol–gel method

Abstract

Silica coatings with high-transmittance and excellent environment-resistance property were prepared by adding hexamethyldisilazane (HMDS) into acid-catalyzed through sol–gel method.

Preparation of silica coatings with continuously adjustable refractive indices and wettability properties via sol–gel method

“…Hydrophobic or hydrophilic property draw much attention about coating's wetting behavior. [21][22][23][24][25] As an essential aspect of surface chemistry, the wettability control of the coating surface shows enormous value in both fundamental research and practical applications. [26][27][28] Two crucial factors have been demonstrated to explain the surface wetting behavior.…”

Bio-inspired self-assembly of waxberry-like core-shell SiO2@TiO2 nanoparticles towards antiglare coatings

“…24 It is known that SiO 2 has excellent properties such as low reective index, low dielectric constant, chemical stability and corrosionresistant property. [25][26][27] Otherwise, TiO 2 has been widely applied in many different kind of coating by compounding with other material, such as SiO 2 and Al 2 O 3 , as an important functional coating inorganic material. Because of high refractive index of TiO 2 , the lm coated TiO 2 has broadband antireection properties to be applied to different kinds of functional coating, which make it extremely attractive for practical applications in optical devices, display devices, and photovoltaic cells.…”

Robust operation of mesoporous antireflective coatings under variable ambient conditions

“…23,24 Co-condensation methods generally combine conventional silica with hydrophobic silane precursors. 17,[25][26][27][28] Experimental procedures are hampered by extensive sol aging times, often on the scale of days or weeks. 17,[25][26][27] Furthermore, consideration must be given on the role and compatibility of the organic component and how it influences the hydrolysis and condensation processes.…”
