Abstract

original image

A superhydrophobic coating on gold threads (see Figure) has been fabricated by combining layer-by-layer assembly, electrochemical deposition, and surface modification. It can be used to mimic the legs of water striders, potentially leading to an understanding of the mechanism of structure reducing and quick propulsion.
