“…Recently some new self-cleaning systems have been proposed utilizing the photocatalytic effect for the degradation of organic pollutants adsorbed on a surface (Yusof et al 2018). Moreover some "smart" surfaces have been also developed and the self-cleaning effect can be UV (Kaner et al 2017;Pifferi et al 2015) or laser-induced (Zheng et al 2016).…”

It is well established that self-cleaning can be related to the hydrophobic or hydrophilic nature of a surface. Using adsorption chromatography, molecular simulations and wetting dynamics measurements, the self-cleaning properties of a new, strongly water resistant and hydrophilic cystine-containing coordination polymer (CP) were tested. Adsorption isotherms of n-octane and methanol were determined in the range of 313-343 K. Next the isosteric enthalpy of adsorption and the change in adsorption entropy were calculated to explain higher adsorption of methanol than n-butane. Performed chromatographic tests, molecular dynamics simulations and wetting dynamics experiments additionally prove that the Zn(Cys) 2 CP is a promising material for the application in the preperation of self-cleaning surfaces or coatings.

“…The incorporation of TiO 2 NPs into the glass matrix leads to the decrement of the water contact angle. Yusof and co-workers [7] reported a lower value of contact angle 43.0° is obtained by using slightly higher TiO 2 NPs content which is 0.40 mol%. However, the significant findings in the current study show the contact angle value of 43.0° can be achieved by the incorporation of a lower concentration of TiO 2 NPs which is 0.20 mol%.…”

“…where γ 𝑆𝑆 is the solid surface tension and γ 𝐿𝐿 is the liquid surface tension, whereas γ 𝑆𝑆𝐿𝐿 is the solidliquid interfacial tension. The shape of a droplet is measured through the contact angle θ and surface tension of the liquid (water) which relates to W A through the equation of Young-Dupré below [7,9,10]:…”

“…Despite these techniques, it comes with their own drawbacks such as high-temperature requirements probably changing the TiO 2 microstructure and these techniques are economically nonviable [6]. Yusof et al [7] fabricates glass containing TiO 2 NPs and demonstrates an extensive study on the thermal, optical, structural, and wettability properties. By using TiO 2 NPs concentration in the range of 0.1 to 0.4 mol%, they found the wettability properties are strongly dependent on the photocatalytic properties of glass.…”

Self-cleaning glasses became demanding for various advanced applications due to their manifold advantages. In this view, some tellurite glasses containing TiO2 nanoparticles with varying concentrations were synthesized using the standard melt-quenching. These glasses were transparent with a reddish appearance. The HRTEM images of the glasses showed the presence of ellipsoidal TiO2 NPs with sizes ranging from 9−22 nm and 5−9 nm along the major and minor axis, respectively. The lattice fringe pattern of the selected TiO2 NPs confirmed their anatase structure with a lattice spacing of 0.36 nm. The observed reduction in the water contact angle from 67.5° to 43.0° of the glasses indicated their hydrophilic nature. The high work of adhesion (0.101− 0.126 N.m-1 ) of the glasses revealed the strong interfacial attractive force between water and glass. It was demonstrated that by adjusting the TiO2 NPs contents the hydrophilic traits of the glassed can be tailored, indicating the suitability for self-cleaning applications.

Cam, keşfedildiği dönemden günümüze dek çok farklı uygulama alanlarına sahip olmuş ve her geçen gün gelişen teknoloji sayesinde ilerleme kaydetmiştir. Cam yüzeylere uygulanan kaplama yöntemleri sayesinde, üretilen cam malzemeler mevcut özelliklerinin ötesinde daha fazla işlevsellik edinmişler, böylece, dış ortam koşullarına karşı (ısı, ışık, zararlı ışınlar, basınç) daha yüksek dayanım sergilemeye başlamışlardır. Bu çalışmada da, cam yüzey kaplamaları hakkında kısa bir tanımlama yapılmış, kaplama teknolojilerinin geçmişten günümüze tarihsel gelişiminden bahsedilmiş, örneklerle cam yüzeyine uygulanan kaplama yöntemlerinden söz edilmiş, kaplama çeşitleri üzerinde durulmuş ve yüzey kaplama teknolojilerindeki son gelişmelere değinilmiştir.
