The evaporation behavior of a sessile droplet on the nano/microstructured surfaces is investigated experimentally in this paper. Three typical modes of evaporation of water droplets on surfaces are observed: one at constant contact radius (CCR), one at constant contact angle (CCA) and a mix of CCR and CCA. The CCR mode is the dominating evaporation mode for water droplet on the nano/microstructures surfaces even if the initial contact angle is larger than 90 degree. The pinning of the three-phase contact line is significant and large spreading coefficient is obtained at the nano/microstructured surfaces.
