Abstract

original image

Janus microspheres composed of two hemispherical surfaces with distinctly different surface complexities show strongly contrasting water affinities between the two halves. As S.-H. Kim, S.-Y. Lee, and S.-M. Yang describe in their Communication on page 2535 ff., the microspheres were prepared by a simple process that commences with Pickering emulsion droplets. Placing the Janus particles at an air–water interface resulted in the formation of a highly flexible and robust superhydrophobic membrane.
