Surface Energy and Work of Adhesion of Titanium Oxide Related Materials
Surface energy and work of adhesion of titanium oxide related materials were investigated. Titanium oxide (TiOx) films were deposited by electron-beam evaporation system using TiO2 as a source material. The films deposited by various thickness and growth rate were etched subsequently by different plasma using various gases like Ar and O2. TiOx films were further modified by self-assembled monolayer (SAM) of silanes and ultraviolet (UV) irradiation. The surface modified TiO, films showed a wide range of water contact angles from 6.9° to 75.2°. The surface energies of Titania-related films and their work of adhesion with human blood were varied with different surface modification process. X-ray photoelectron spectroscopy (XPS) revealed that hydroxyl group present on the surface explains the hydrophilicity of the surface modified TiO, films. We also suggest that some surface modified samples can provide an excellent hemocompatible surface from the estimated work of adhesion between the surface modified TiO, samples and human blood.
