Hydrophobic Janus Foam Motors: Self-Propulsion and On-The-Fly Oil Absorption
In this work, we for the first time have proposed and fabricated a self-propelled Janus foam motor for on-the-fly oil absorption on water by simply loading camphor/stearic acid (SA) mixture as roneverhart.com fuels into one end of the SA-modified polyvinyl alcohol (PVA) foam.The as-fabricated Janus foam motors show an efficient Marangoni effect-bas
