Wettability of Graphene Oxide/Zinc Oxide Nanocomposite on Aluminum Surface Switching by UV Irradiation and Low Temperature Annealing

Zinc oxide (ZnO) nanoparticles were grown on graphene oxide (GO) surface via reflux method. Electrophoretic deposition (EPD) process was employed to deposit graphene oxide/zinc oxide (GO/ZnO) nanocomposite on Al plate with 1 mg/ml of GO/ZnO suspension, 30 V and 3 min. X-ray Diffraction (XRD), X-ray...

Description
Summary:Zinc oxide (ZnO) nanoparticles were grown on graphene oxide (GO) surface via reflux method. Electrophoretic deposition (EPD) process was employed to deposit graphene oxide/zinc oxide (GO/ZnO) nanocomposite on Al plate with 1 mg/ml of GO/ZnO suspension, 30 V and 3 min. X-ray Diffraction (XRD), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscope (SEM), energy-dispersive X-ray spectrometry (EDX) and elemental mapping (MAP) investigation were used to characterize the samples. The hydrophobic and hydrophilic behavior of samples were obtained by heat treatment and UV irradiation, respectively. Heat treatment and UV-irradiation affect wettability of samples. Moreover, switchable wettability of samples was investigated. The WCA changes from 5° to 137° by heat treatment and vice versa by UV-irradiation. Graphic Abstract
