Enhancing glass surface hydrophobicity: the role of Perfluorooctyltriethoxysilane in advanced surface modification
This study presents a novel approach to fabricate self-cleaning, superhydrophobic coatings on glass surfaces and photovoltaic cells. Using a cost-effective spray-coating technique, superhydrophobic glass surfaces were developed incorporating modified SiO2 nanoparticles (NPs), synthesized via a simple sol–gel method. Silylating agents, Poly(dimethylsiloxane) (PDMS) and Perfluorooctyltriethoxysilane (PFOS), were used for the modification, resulting in enhanced surface roughness and hydrophobicity. The study extensively characterizes the analytical techniques such as Fourier transform infrared spectroscopy (FT-IR), atomic force microscopy (AFM), transmission electron microscopy (TEM), scanning electron microscopy (SEM), and contact angle measurements. Modified NPs with PFOS showed a significant improvement in hydrophobic properties, with water contact angles of 144.73° and sliding angles of 5°. The stability of these surfaces under various pH conditions was also evaluated. This research contributes valuable insights into the development of self-cleaning coatings for glass and photovoltaic cells, demonstrating the potential of superhydrophobic surfaces in practical applications.
期刊介绍：
The primary objective of the Journal of Sol-Gel Science and Technology (JSST), the official journal of the International Sol-Gel Society, is to provide an international forum for the dissemination of scientific, technological, and general knowledge about materials processed by chemical nanotechnologies known as the "sol-gel" process. The materials of interest include gels, gel-derived glasses, ceramics in form of nano- and micro-powders, bulk, fibres, thin films and coatings as well as more recent materials such as hybrid organic-inorganic materials and composites. Such materials exhibit a wide range of optical, electronic, magnetic, chemical, environmental, and biomedical properties and functionalities. Methods for producing sol-gel-derived materials and the industrial uses of these materials are also of great interest.
