Nanocomposite Based Multifunctional Coatings

摘要: The function of automotive coatings so far has been twofold – decoration and conservation. former not only consists providing a coloured smooth surface but also to accentuate the shape car body via viewing angle dependant brightness / or colour. These optical effects mostly rely on tiny mirrors metal flakes like aluminium coated mica platelets that are more less homogeneously dispersed within one coating layer; their normal predominantly being orthogonal substrates surface. particles lateral dimensions typically in order several hundred microns. role conservation metallic mainly protection substrate towards electrochemical degradation (= corrosion) either actively barrier layer as well best possible limitation defects produced wake dramatic mechanical perturbations impacting gravel stones. On contrary mounted plastic parts panels most cases have be protected against chemical triggered by exposure UV light, physical erosion swelling solvents fuel water depending nature polymers morphology bulk catastrophic failure part upon impacts brittle crash behaviour). means achieve latter similar those used design stone chip resistant for bodies.
