Silica and Silane based polymer composite coating on glass slide by dip - Coating Method

Superhydrophobic coatings are widely used for various engineering applications, namely, self-cleaning and self- healing for engineering structures. Therefore, in recent decades, a number of industries have shown significant interest in the development of superhydrophobic coatings for various purposes. In view of the above demands, this study presents explicitly a cost-effective and facile method to fabricate superhydrophobic transparent coating on the glass. The superhydrophobic coating was prepared by dip-coating technique with sol-gel of polymethyl methacrylate-co-ethyl acrylate polymer (PMMA), SiO 2 nanoparticles (SiNps) and 1H, 1H, 2H, 2H perfluorooctyltrichlorosilane (PFOTS). Wettability, surface morphology, and the transparency of coating were investigated. Also, the stability of the coating was assessed at harsh conditions like annealing at high tem- peratures (4-400 degrees C), irradiation by UV light, and pH resistance at different alkali and acidic conditions (2-13), and mechanical durability by performing water-jet, abrasion and adhesion tests were studied. The coated glass exhibits a static water contact angle (CA) of 174 +/- 2 degrees and with a sliding angle (SA) of 4 +/- 1 degrees Furthermore, the coating exhibits excellent self-cleaning property, and more than 91% of the transparency of the coating was assessed. All the results indicated that such type of coatings could also use for self-cleaning and transparent coatings at the industrial level.
