Abstract

original image

On page 5486, Yongmei Zheng, Lei Jiang, and co-workers report that geometrically engineering thin fibers by introducing hump structures, similar to wetted spider capture silk, greatly improves the adhesion of the fibers to drops. An unusual three-phase contact line extends axially along the fibers to achieve stability of the contact line through a combination of “slope” and “curvature” effects. This creates sufficient capillary adhesion to pin the larger hanging drops to the fibers.
