Janus Microspheres for a Highly Flexible and Impregnable Water-Repelling Interface

Janus microspheres composed of superhydrophobic and hydrophilic hemispherical surfaces were prepared using photocurable Pickering emulsion droplets. Upon placement at an air–water interface, an impregnable superhydrophobic barrier with high flexibility is formed. These microspheres have great potent...

Description
Summary:Janus microspheres composed of superhydrophobic and hydrophilic hemispherical surfaces were prepared using photocurable Pickering emulsion droplets. Upon placement at an air–water interface, an impregnable superhydrophobic barrier with high flexibility is formed. These microspheres have great potential in size‐dependent semipermeable membranes, floating micromachines, and superhydrophobic coatings.
