Steuerung der Benetzungseigenschaften von optisch transparenten Polymeren durch Antireflexstrukturen und dünne Schichten

Controlled wetting of optical polymers by antireflective structures and thin films The wetting behaviour of antireflective structures can be modified by additional coatings to become superhydrophobic or hydrophilic. The sub‐wavelength structures which increase the samples transmission are generated by plasma etching. Bump structures with large aspect ratio show a Lotus‐like behaviour immediately after coating with a thin hydrophobic layer. In case of PMMA the Lotus‐state can only be achieved if a thin silica layer is arranged below the hydrophobic top‐layer.
