Antibacterial Activity of Hydrophobic Composite Materials Containing a Visible-Light-Sensitive Photocatalyst
Figure 2
Scanning electron micrograph of the surface of a sample composed of 80 wt% PTFE, 8 wt% N-doped TiO2, fluoro-oil and the remainder of fluorine binder. The water repellent property of the sample is attributed to the surface roughness created by the PTFE particles.
