Nanocoating

Nanocoating is a nano technological coating technique that is applied on objects, creating an superhydrophobic or superhydrophilic surface. The main use of such coating on objects is to repel liquids off the surfaces.

    Waterproof coating

    Nanocoating is the result of an application where nano structures build a consistent network of molecules on a surface. This entails the chemical process where the surface can be designed to become (super) hydrophobic or hydrophilic for example. Nanocoating is a growing line and some of its applications are already in use whereas many more, with great potential, are being researched on. In this article we will look at the top 8 applications of nanocoating that is currently being used.

    Optische Komponenten begleiten uns in nahezu allen Alltagsanwendungen – von Handykameras über Abstandssensoren in Autos bis hin zu Objektiven für hochauflösende Kameras. Doch ohne Entspiegelung gehen an jeder Grenzfläche einer optischen Komponente mehrere Prozent des Lichtes verloren. Deshalb sind heute insbesondere Systeme aus mehreren Linsen wie z.B. in Fotoapparaten oder Fahrzeugdisplays ohne Antireflex (AR)-Funktion undenkbar. Forschern gelang es nun, erfolgreich eine neue Methode der Entspiegelung mithilfe nanostrukturierter Schichtmaterialien zu entwickeln.

    Most lenses, objectives, eyeglass lenses, and lasers come with an anti-reflective coating. Unfortunately, this coating works optimally only within a narrow wavelength range. Scientists at the Max Planck Institute for Intelligent Systems in Stuttgart have now introduced an alternative technology. Instead of coating a surface, they manipulate the surface itself. By comparison with conventional procedures, this provides the desired anti-reflective effect across a wider wavelength range. But more than this, it largely increases the light transmittance through surfaces.
