摘要：

A reconfigurable, droplet-directing surface is developed based on high-aspect-ratio shape-memory polymer (SMP) pillars. The water droplet on the original or recovered SMP pillars can slide off the surface at a finite angle of inclination while being fully pinned on the deformed pillar array. This wettability contrast allows directed water shredding from the straight pillars to the deformed ones. © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
