Durable superhydrophobicity in embossed CYTOP fluoropolymer micro and nanostructures Durable Superhydrophobicity in Embossed CYTOP Fluoropolymer Micro and Nanostructures
Abstract: Micropillars, nanopillars and dual scale micro-nanopillars were fabricated out of an inherently hydrophobic amorphous CYTOP fluoropolymer by hot embossing. The resulting pillars were superhydrophobic with high apparent contact angles (θ > 160°) and low rolling angles. Abrasion experiments were performed using a novel rotary abrasive slurry setup. Due to their inherent hydrophobicity, CYTOP micro and nanopillars retained their superhydrophobic properties even after 4 hours of abrasion (900 rpm in 10 % slurry of 30 μm alumina particles), unlike control samples prepared out of fluoropolymer coated silicon
