Investigation of surface energy, wettability and zeta potential of titanium dioxide/graphene oxide membranes
Abstract
<p>This research aims to study the wettability and zeta potential of photoactive TiO<sub>2</sub>/GO composite membranes. Full factorial design was utilized for the investigation of the influence of TiO<sub>2</sub> content, reduction temperature and UV activation on the surface energy and zeta-potential of TiO<sub>2</sub>/GO composite membranes. Multivariate data analysis of FTIR data was used to correlate the changes in wettability and zeta-potential after UV irradiation to changes in surface functional groups of the TiO<sub>2</sub>/GO membranes. The hydrophilic properties of pure GO (D) and TiO<sub>2</sub>/GO composite membranes (A, B, and C) is highly dependent on reduction temperature; membranes reduced at 140 °C have significantly higher surface energy than membranes reduced at 160 °C. Principal component analysis (PCA) of Fourier transformation infrared spectroscopy (FT-IR) data, thermogravimetry analysis (TGA) and differential scanning calorimetry (DSC) analysis shows that the change in surface energy was a result of loss of carboxylic acid and hydroxyl groups when reduced at 160 °C. The largest change in surface energy was observed after UV activation of the TiO<sub>2</sub>/GO membranes. From the PCA model the increase in surface energy is caused by an increase in OH groups on the TiO<sub>2</sub> after activation of the TiO<sub>2</sub>/GO membrane. Moreover higher TiO<sub>2</sub> content was found to significantly increase the surface energy of the membranes. TiO<sub>2</sub>/GO membranes with higher TiO<sub>2</sub> contents showed faster hydrophilic conversion rates. In addition the Zeta potential of the membranes changes significantly resulting in more negative zeta potentials after UV activation which enhances the electrostatic repulsion of negatively charged fouling components. The zeta potential of the individual TiO<sub>2</sub>/GO membranes was found to be almost constant in the pH interval 4–9.</p>
