Surface hydrophobicity changes of a series of nanocomposite films were evaluated as a function of roughness and ionomer concentration. Nanocomposite surfaces were created by coating a smooth silicon wafer and micro textured surfaces based on two types of 3M micro-replicated Brightness Enhancement Films (BEF). Multiple nanocomposite surfaces were evaluated as a function of Pt/C catalyst, a single walled carbon nanotube (SWCNT), and ionomer concentration varying between 7.5 to 27.3 wt% Nafion. An increase in hydrophobicity was observed for all nanocomposite surfaces as compared to bare substrates coated with ionomer. Bare substrates had observed water contact angles of 32.5o on silicon, 50.8o on BEF type Y, and 91.2o on BEF type P. Nanocomposites coated on BEF type P surfaces had the greatest increase in apparent contact angle starting from 101.5o on a surface coated with ionomer to 140.6o for an ionomer composite containing 100 wt% Pt/C followed by BEF type Y (78.4o - 135.4o) and Si (76.9o - 135.8o). Nanocomposite roughness increased with increasing ionomer concentration and was inversely related to the apparent contact angle of water. Nanocomposite wetting properties were strongly dependent upon ionomer concentration and micro scale roughness contributed to wetting behavior transitioning between Wenzel and Cassie modes.
