Room temperature curable inorganic–organic hybrid nanocomposite single layered transparent hard hydrophobic coatings have been developed by sol–gel spray coating process.
Single layer design ZrO 2 incorporated TiO 2 based transparent hard reflecting nanocomposite coatings on glass substrates were developed by sol-gel dip-coating technique using zirconium (IV) n-propoxide (ZP) and titanium (IV) isopropoxide (TTIP) followed by heat treatment at 500 °C for 1 h. The above nanocomposite based TiO 2-ZrO 2 coated glass could be used as component for efficient energy saving building materials with esthetic beauty. The TZ85:15 coated glasses (dimension: 200 × 200 mm 2) with coating thickness 90 ± 10 nm having refractive index value of 1.985 ± 0.002 were found to be flawless with good hardness ~ 5H and adhesion properties. GIXRD and Raman analysis of specimens revealed the crystalline nature of the heat-treated coatings, whereas the formation of Ti-O-Zr network was observed by XPS and FTIR. Coated glass showed > 28% of average reflection (within wavelength range of 350-2500 nm) and ~ 31% (within wavelength range of 400-800 nm). It also revealed the golden yellow reflected color under tube-light exhibiting enhanced aesthetic beauty making suitable candidate for heat reflecting component.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
