Surface modification treatments able to confer antistain/antibacterial properties to natural or synthetic materials are receiving increasing attention among scientists. Ion beam co-sputtering (IBS) of zinc oxide (ZnO) and poly-tetrafluoroethylene (PTFE) targets allows for the preparation of novel multifunctional coatings composed of antimicrobial ZnO nanoparticles (NPs) finely dispersed in an antistain PTFE polymeric matrix.*
In the article “New Insights in the Ion Beam Sputtering Deposition of ZnO-Fluoropolymer Nanocomposites” Maria Chiara Sportelli, Marco Valentini, Rosaria Anna Picca, Antonella Milella, Angelo Nacci, Antonio Valentini and Nicola Cioffi describe the use of X-ray photoelectron spectroscopy (XPS), atomic force microscopy (AFM), and transmission electron microscopy (TEM) for the characterization of the IBS deposited coatings in order to obtain information on the materials’ surface composition, with deep insight into the nanocoatings’ morphology as a function of the ZnONP loadings.*
The AFM micrographs shown in this article were acquired on 150-nm-thick films in dynamic (“tapping”) mode, in air, using NanoWorld Pointprobe® NCL AFM probes.
