Various Hydrophobic hairy carbonaceous fibers (HCF) are obtained by low-temperature chemical vapor deposition (CVD) process on catalyst-patterned surface, patches of which are selectively coated with silica to make the surface superhydrophobic and yet allow strong water adhesion for the ‘Salvinia effect.” Due to its hairy fibers’ unique properties, when a droplet of water is dropped upon its leaf’s surface, it looks as if the leaf is holding on to the droplet. Using this property, the research team artificially created the Salvinianatan’s leaf to materialize gas-liquid interfacial property. Through such means, the team has opened a way to reduce large amounts of fuel. Moreover, “a new membrane-free microfluidic device for inverted gas-liquid biphasic chemical process has been introduced.”
Prof. Kim’s research on HCF was published in Advanced Materials Jun. 28, 2013.
