New Surface Makes Oil Contamination Remove Itself (VIDEO)

Aalto University

Caption

Researchers of Aalto University have developed surfaces where oil transports itself to desired directions. Researchers' oleophobic surfaces are microtextured with radial arrays of undercut stripes. When oil drops fall on surfaces, drops move away from the landing point to the direction set by asymmetric geometrical patterning of the surface. The surfaces open up new avenues for power-free liquid transportation and oil contamination self-removal applications in analytical and fluidic devices.
