Yuchen Wu, Xiao Chen, Bin Su, Yanlin Song and Lei Jiang Elaborately Aligning Bead-Shaped Nanowire Arrays Generated by a Superhydrophobic Micropillar Guiding Strategy Advanced Functional Materials 22
Regularly aligning bead-shaped nanowire arrays are generated, assisted by highly adhesive superhydrophobic pillar- structured silicon substrates. The bead-shaped structures can be introduced by either Rayleigh instability at ultralow polymer concentration or rigid polystyrene spheres serving as bead building blocks. Furthermore, bead-shaped nanowires have the unique ability to directionally drive tiny drops and collect coalesced microdroplets when placed in mist.
