Fabrication and Properties of Hydrophobically Modified ZnO–SiO2 Nanocomposite with Polysiloxane

Studies on the wettability properties of solid surfaces are very important in any scientific and industrial fields. The most common principle for a superhydrophobic self-cleaning surface is lotus effect induced by roughness. In this study, silicate compounds have been used to produce hydrophobic surfaces. way, firstly, SiO2–ZnO nanocomposite was produced, then vinyl trimethoxy silane increase water contact angle (WCA). structure morphology nanocomposites were investigated infrared spectroscopy (FT-IR), X-ray diffraction pattern (XRD), scanning electron microscopy (SEM) energy-dispersion spectrometer (EDS) analyses. thermal stability coatings examined thermogravimetric analysis (TGA). order investigate wetting properties, roughness measured using an atomic force microscope (AFM), where subsurface average obtained at 37.79 nm. WCA coated with ZnO–SiO2 @Polysiloxane 69 160°, respectively, indicating nanocomposites. Finally, Cassie-Baxter model. value f2 parameter model estimated 0.9556. This means that air occupies about 95.56% area between droplet nano-coating, which responsible property surface.
