摘要

A unique water collection ability is revealed in green bristlegrass bristle that is attributed to a barb array similar to the ratchet structure that is arranged on the cone groove surface of bristle. The multi-level geometric gradients are formed to dominate the coalescence and directionally transport the tiny droplets of condensed water.
