ÖZET: Bir tekstil yüzeyinin ıslanabilirliği esas olarak yüzeyin kimyasal yapısı ve yüzey pürüzlülüğüne bağlı olarak değişmektedir. Bilim dünyası doğada kendini temizleyebilme özelliğine sahip nilüfer yaprağı gibi nanopürüzlü yüzeylerin biyobenzetim tekniği ile benzerini üretmeyi esas alan yöntemler ve malzemeler geliştirmektedir. Bu çalışmada, tekstil yüzeylerinin ıslanabilirliği, ıslanma teorisi ve ortam şartlarına bağlı olarak ıslanabilirliği değişen yüzeyler ele alınmıştır. Bu yüzeylerin; sıcaklık, pH, ışık veya elektrik alan etkisi altında yüzey kimyası ve konformasyonunun değişimi incelenmiştir. Anahtar Kelimeler: Temas açısı, süper hidrofobluk, biyobenzetim, uyarı-cevap esaslı ıslanabilirlik Switchable Wettability On Textile Surfaces Using Nanotechnology ApplicationsABSTRACT: Wettability of a textile surface basically depends on chemical structure and roughness of surface. Science world has developed new methods and materials using biomimetics to obtain nanorough surfaces like lotus leafs which have self-cleaning feature. In this study, wettability of textile surfaces, theory of wettability and production of nano surfaces having stimuli-responsive wettability were discussed. Alteration of surface chemistry and conformation under the effects of temperature, pH, light or electrical field were examined.

“…It was found that this film had minimal impact on solar cell. However, the superhydrophobic surfaces formed by ZnO micro-nano structure are easy to lose their superhydrophobicity under sunlight because of photooxidative ability (Li et al, 2013). The wettability switch under UV irradiation from superhydrophobicity to superhydrophilicity on the surface of ZnO is caused by photochemical reactions (Feng et al, 2004).…”

ZnO nanorod arrays were fabricated on glass through hydrothermal way. Then a thin SiO 2 film was covered on ZnO nanorod arrays using pulsed laser deposition (PLD) technique, and modified by stearic acid. It was found that SiO 2 film only had slight effects on the contact angle and transmittance of ZnO nanorod arrays. However, it had brought a huge improvement in the UV durability of superhydrophobic ZnO nanorod arrays. The results showed that the water contact angle remains constantly at 160.5 • even UV irradiation time exceeded 50 h when the deposition time of PLD was about 10 min. This structure with UV-durable superhydrophobicity and highly transmittance on glass substrate can be served as front materials in solar cells.

“…Coatings displaying different wettability to temperature can be used in oil-water separation, microfluid device, functional textiles, filters and controlled drug release [10,15,16]. Furthermore, this kind of special coatings also can be utilized for anti-corrosion, anti-fog, anti-icing, drag reduction, pharmaceutical, self-cleaning, water recycling, shielding, solar cells and sensors [17,18].…”

A one-step electrodeposition method was utilized to fabricate coatings with switchable wettability on stainless steel meshes to extend the application of materials in the intelligent material industry. This method did not involve low surface energy materials and had advantages of simple and good repeatable. Through changing pH value, deposition temperature and voltage, the relationship between morphology and wettability of the as-prepared coatings were studied. The SEM results show numbers of particles on the coatings under the optimum condition and some of them aggregated into micropine hierarchical structures. The coatings achieved superhydrophobicity with a contact angle of 155.5°. After being placed at 450°C for 3 h, the superhydrophobic film turned into superhydrophilic. The film regained superhydrophobicity after hydrothermal treatment in glucose aqueous solution, which exhibited a reversible transition between superhydrophobicity and superhydrophilicity. In addition, the superhydrophilic coatings could be used to separate light oil, such as diesel, gasoline, toluene, benzene and lubricants, excellent oil-water separation ability of 95%.
