Abstract
In this work, we report the effects of oleic acid as surfactant on the growth properties of hydrothermally-synthesized BaTiO3films by chemical modification of Ti sheets. Hydrothermal process was carried out in an aqueous solution of Ba(OH)2 with different oleic acid concentrations and using NaOH as mineralizer. Microstructural properties and chemical composition were studied by X-ray Diffraction (XRD), X-ray Photoelectron Spectroscopy (XPS) and Scanning Electron Microscopy (SEM). This study represents an interesting starting point for the future synthesis of nanostructured BaTiO3 thin films with optimized properties for potential applications in Flexible Capacitors (FCs).
