Surfaces (technologie)Index. décimale : 667.9 Revêtements et enduits Résumé : Nanoscale titanium dioxide (TiO2) films were deposited on the surface of polyester nonwovens by using direct current (DC) reactive magnetron sputtering. The effect of coating thickness on the surface structures and properties of TiO2 coated fabrics was investigated by atomic force microscope (AFM), X-ray diffraction (XRD), energy dispersive X-ray analysis system (EDX), scanning electron microscope (SEM), and antistatic test in this article. The results indicated that the grain sizes of the sputtered clusters increased and the coating layer became more compact as film thickness was increased, but the crystal structure did not have any significant change. At the same time, the film mechanical properties and antistatic performance in general depended strongly on the film thickness which could lead to the optimum thickness for a particular application.

Revêtements multicouchesIndex. décimale : 667.9 Revêtements et enduits Résumé : In this study, we describe a new technique for creating dense, stable, nanolayer coatings on solid substrates using ultrasonic nebulization. Nebulization-assisted layer-by-layer assembly (LbL) is a modification to the well-characterized LbL assembly method. The conventional method of producing electrostatically assembled multilayer films through sequential substrate dipping was compared to the nebulization method, and the resultant film characteristics were investigated. Varied coatings can be generated according to the alterations in deposition parameters, with the most influential being nebulizer distance and time. In addition to employment of polyelectrolytes (PEs), the nebulization method has been extrapolated to generate assemblies containing nanoparticles and a model drug, dexamethasone. It is shown that in comparison with conventional LbL, similar bilayers’ layering thicknesses can be achieved within a much smaller timeframe. Furthermore, PEs and more complex protein and nanoparticle assemblies can be incorporated to influence the surface topography and functionality. The potential to expeditiously assemble multicomponent films has far-reaching implications in many focus areas.

Spectroscopie d'impédance électrochimiqueIndex. décimale : 667.9 Revêtements et enduits Résumé : The coating process in the industry segment of mobile machinery for ACE, e.g., agricultural machines, is usually done by spray application after welding a variety of parts on the framework. The current painting process consists of an anticorrosive primer and a weather-resistant topcoat. The presented study is part of a research project investigating a new concept combining a new sequence in construction with the big advantage of applying a single-coat system. This smart production enables the construction of machines in modules, keeps the volume of an electrocoating dipping bath at a minimum level, and replaces the custom painting procedure with much overspray by an economic and ecological coating technology. To realize this new technology, the coating system has to perform as an anticorrosive system, providing a sufficient outdoor weather resistance, and must have sufficient adhesion strength for structural bonding of additional parts. First results show that the investigated electrocoats show good anticorrosive properties. The UV- and the weather resistance meet the required values (> 50% gloss retention after 1000 h artificial weathering of CAM 180), dependent on the type of electrocoat. First investigations on structural bonding show that a high bonding strength can be achieved.
