“…Therefore, epoxy resin (EP) has been progressively used to prepare composite coatings because of its good adhesion and corrosion resistance [93]. Li et al reported a hydrophobically modified TiO 2 with fluorine-containing hydrogen-containing polysiloxane (F-PMHS) [94]. They prepared an M-TiO 2 @EP superhydrophobic composite coating on the glass substrate using EP as the adhesion, which achieved a static contact angle of over 153 • for water droplets in a wide pH range (Figure 11e,f).…”

To address environmental pollution and energy shortage issues, titanium dioxide (TiO2)-based photocatalysts, as an efficient pollution removal and fuel production technology, have been widely used in the field of photocatalysis. In practical applications, TiO2-based photocatalysts are usually prepared on various substrates to realize the separation of the catalyst from water and improve photocatalytic stability. Herein, the research progress of TiO2-based heterogeneous photocatalytic coatings deposited on glass substrates with various deposition techniques is reviewed. Such TiO2-based composite coatings obtained using different techniques showed excellent self-cleaning, pollution removal, air purification, and antibiosis performance. The various deposition techniques used for the preparation of TiO2 coatings, such as wet chemical deposition (WCD), electrodeposition, physical vapor deposition (PVD), and chemical vapor deposition (CVD) were discussed together with photocatalytic applications by highlighting the typical literature. Finally, the challenges and prospects of developing TiO2-based heterogeneous coatings were put forward.

“…These kinds of coatings are also useful for increasing the efficiency of solar cells by making the surface exceptionally transparent and self-cleaning. The fabrication of these coatings can either be performed by expensive techniques like PVD [4], CVD [5], or by in-expensive sol-gel based techniques like spin coating [6], dip-coating [7] and spray pyrolysis [8]. Xia et al developed hydrophobic self-cleaning coating using composite titania and silica [9].…”

The pollutants from the environment can also degrade the surface of the glass, which result in loss of transmittance of the glass surface. This necessitates the formation of a dedicated crew for the correct maintenance of glass furniture, notably in the Middle East. In this paper, we describe sol-gel spin coating of titania thin films on glass substrates, which may function as a hydrophilic coating by spreading water molecules across the substrate and removing pollutants and other dust particles, hence eliminating the need for maintenance and wipers. The fabricated coating was tested with X-ray diffractogram (XRD) and evidenced anatase nature of titania and amorphous nature of silica at Bragg angle 25° in the coating. Fourier transform infrared spectroscopy (FTIR) investigations endorsed Ti-O-Ti and Si-O-Si functional linkages at wavenumbers 551, and 957 cm-1 demonstrating the presence of titania and silica in the as-developed coating. Cross sectional field emission scanning electron microscopy (FESEM) investigation evidenced the formation of composite titania-silica film on the glass substrate with a thickness about 36 nm. The coating transmittance was studied by ultraviolet-visible and near-infrared (UV-Vis-NIR) spectroscopy and found 95% transmittance in the visible region. Moreover, wetting study utilizing the sessile drop technique yielded a 74° contact angle when the water droplets were interacted.
