Fabrication of porous TiO₂–SiO₂ multifunctional anti-reflection coatings by sol–gel spin coating method

Abstract

Fabrication of a self-cleaning anti-reflection coating that can degrade gaseous pollutants and applied contaminants to maintain long-term transmittance property.

Ultra-high aspect ratio functional nanoporous silicon via nucleated catalysts

“…Nanostructured TiO 2 has been explored for applications owing to its anti-reective and self-cleaning properties. [57][58][59] Fig. 2f shows reectivity measurement TiO 2functionalized NPSi, demonstrating reectance values between 2% and 8% over the UV-visible and short-IR wavelengths for both Au-and Ag-etched Si.…”

“…Super-hydrophilic coatings, made of polymers or metal oxides, have great potential for anti-fogging, self-cleaning, anti-fouling, fog-harvesting and so on. [1][2][3][4][5][6][7][8][9] The super-hydrophilicity can be fabricated either by micro-/nano-scale structure or by high surface concentrations of functional (e.g., hydroxyl) groups. [10][11][12][13][14][15][16][17] Silica is one of the widely used super-hydrophilic materials with superior transparency and anti-fogging performance due to the high surface concentration of hydroxyl groups.…”

Innovative Bioactive Ag-SiO2/TiO2 Coating on a NiTi Shape Memory Alloy: Structure and Mechanism of Its Formation

“…The different chemical environment that was observed for the sintered material was also reflected by the interpretation of the Ti 2p core line. Here, the most intensive line (459.2 eV) was assigned to the titanium dioxide, while an atypical line at higher binding energy (460.3 eV) may correlate with the surface modification within the TiO 2 interlayer or the formation of the structurally defected titanium dioxide [ 56 ]. The stronger titanium signal of the deposited coating could have resulted from the microporosity that formed due to the surface infiltration of water vapor; however, the continuity of the layer was not broken according to the SEM observations ( Figure 1 d).…”
