“…Multilayers AR coatings generate AR efficiency in the broader wavelength region or multi-dip in the desired wavelength range [49,50] . The SiO 2 , TiO 2 multilayer AR coatings are a most common combination of composite AR coating used as high and low index coating for achieving AR in a broader region on glass substrates [51,52] . There are various factors which limit usage of multilayer AR coatings, such as in the multilayer stack adhesion strength at interfaces, mismatch thermal properties of different oxide coatings, complex, intricate e-ISSN: 2321-6212 p-ISSN: 2347-2278 fabrication process, mechanical stability decrement due to multilayer stacks, and expensive cost restricts their usage.…”

Antireflective coatings (AR) are widely applied to eliminate the unwanted surface reflections from the AR coated substrate. In different optoelectronic devices, AR coatings have potential usage in photovoltaic solar cells, sensors, display devices, automobile industries to reduce reflectance, glare and enhance light transmittance. Natural phenomenon inspires researchers, and they generate bionic AR coatings copying the nature such as moth eyes, or cicada wings to fabricate efficient light harvesting AR coatings. In the current review article, we analyse and evaluate critically the progress and recent development in the fabrication of AR thin films comprising organic coatings, inorganic coatings, polymer AR coatings and bionic AR coatings. We predominantly emphasise the AR coatings fabrication by different methods and pinpoints the technological challenges in their real-world reliability. Finally, we address the future challenges and potential strategies for their upcoming prospect.

“…The energy width of the two peaks was approximately 5.9 eV, which revealed the chemical state of Ti to be Ti 4+ . 51 Compared with the standard spectrum, the measured spectrum is slightly blueshied. The Ti2p 3/2 or Ti2p 1/2 peak shied to a lower binding energy by approximately 2 eV compared to the anatase phase of Ti 4+ .…”

a This study differs from previous studies of TiO 2 /SiO 2 in that 0.5-10 mm microsized TiO 2 -rutile based catalysts (TR catalysts) with varying proportions of titanium and silicon were synthesized using a onestep modified hydrothermal method. At Ti/Si ¼ 1/9, a two-dimensional channel-structured catalyst with a morphology resembling that of SBA-15 was obtained. In contrast, at Ti/Si ¼ 3/7 or 5/5, a threedimensional porous structure was formed, and Ti-O-Si-C bonds appeared. The structure of the TR catalyst transformed due to the decrease in C-Si bond content and the increase in C-C bond content with increasing Ti/Si ratio. The results indicated that the rutile phase was the main crystal phase of the TR catalyst. The small crystal size and large rutile phase content of the mesoporous TR catalyst contributed to the low band gap energy below 3.0 eV. Under 2 Â 10 W lamp irradiation with either UVA or visible light, the three TR catalysts showed better formaldehyde (HCHO) removal efficiency than P25. Overall, the Pt/TR catalyst is a potential material for pollutant removal and can be easily separated from the pollutant removal system since the catalysts are microsized.

“…Titanium dioxide (TiO 2 ) is a widely used solid filler in the coating industry due to its ability to absorb ultraviolet light and improve the stability and weather resistance of coatings [18,19]. With the intent of taking advantage of these features, we developed mesoporous TiO 2 whiskers (TiO 2 (w)) with a large surface area, high thermal stability, and good mechanical properties [20].…”

Abstract:A novel multi-functional carrier of mesoporous titanium dioxide whiskers (TiO 2 (w)) modified by ethylenediamine tetra (methylene phosphonic acid) (EDTMPA) and imidazoline was devised in epoxy coating to improve the anti-corrosion and scale inhibition properties of metal surface. Rigorous characterization using analytical techniques showed that a mesoporous structure was developed on the TiO 2 (w). EDTMPA and imidazoline were successfully grafted on the outer and inner surfaces of mesoporous TiO 2 (w) to synthesize iETiO 2 (w). The results demonstrated that the corrosion resistance of the final iETiO 2 (w) epoxy coating is 40 times higher than that of the conventional unmodified OTiO 2 (w) epoxy coating. The enhanced corrosion resistance of the iETiO 2 (w) functional coating is due to the chelation of the scaling cations by EDTMPA and electron sharing between imidazoline and Fe. Scale formation on the iETiO 2 (w) coating is 35 times lower than that on the unmodified OTiO 2 (w) epoxy coating. In addition, EDTMPA and imidazoline act synergistically in promoting the barrier property of mesoporous TiO 2 (w) in epoxy coating. It is believed that this novel, simple, and inexpensive route for fabricating functional surface protective coatings on various metallic materials will have a wide range of practical applications.
