Abstract

Researchers report the design and fabrication of a magnetically transformable surface that can switch between the superhydrophobic and slippery states. The surface consists of an array of magnetically responsive hierarchical micropillars that are made out of soft polymeric materials and are conformally infused with a liquid lubricant. The orientations of the lubricated micropillars can be controlled by the direction of external magnetic field. In the superhydrophobic state, the micropillars are oriented vertically so that a liquid droplet only touches the tips of the hydrophobic micropillars.
