Abstract

In this work, graphene oxide (GO) is deposited on steel mesh by anodic electrophoretic deposition (EPD) and then is reduced by low temperature thermal annealing. Morphology of the samples is characterized by scanning electron microscopy (SEM) analysis. X-ray photoelectron spectroscopy (XPS), energy-dispersive X-ray (EDX), Raman and FT-IR analyses confirm the reduction of GO with thermal annealing. The results of water contact angle (WCA) measurements show that the superhydrophilic steel surface is changed to superhydrophobic after deposition of GO and then thermal annealing at 250 °C for 4 h under N2 atmosphere. The prepared superhydrophobic mesh is used for oil/water separation successfully.
