Ultrahigh-Aspect Ratio Microfiber-Furs as Plant-Surface Mimics Derived from Teeth

Ultrahydrophobic surfaces that mimic the surface of a Corokia cotoneaster leaf were created by using cow teeth as natural template. After UV curing of an acrylate resin and removing the template, a highly dense hairy fur‐like structure with high aspect ratio could be obtained. Subsequent modificatio...

Zusammenfassung:Ultrahydrophobic surfaces that mimic the surface of a Corokia cotoneaster leaf were created by using cow teeth as natural template. After UV curing of an acrylate resin and removing the template, a highly dense hairy fur‐like structure with high aspect ratio could be obtained. Subsequent modification with silica nanoparticles and fluorosilane afforded a water contact angle of some 170°.
