SEM images of fabricated samples for LFP tests: (a) smooth Au layer; (b) posts on smooth Au layer; (c) posts on smooth layer; (d) LBL layer. Insets show static equilibrium contact angle on the fabricated samples for water droplets on (a) smooth Au (83°), (b) Au with microposts (83°), (c) layer (19°), and (d) nanoporous layer .
Water droplet evaporation time vs surface temperature. The error bars attached to the filled pink diamond symbols represent the standard deviation of nominally identical tests on the smooth Au-coated surface. The nominal uncertainty in the measurement of the LFP temperature was found to be less than .
Photographs of evaporating water droplets on test surfaces held at : (a) Au without posts; (b) Au with posts; (c) with posts; (d) nanoporous layer with posts. Arrows show location of droplet-to-surface bridging by liquid filaments.
