New Surfaces Repel Organic Liquids (2 of 2)

Caption: A steel grid (square pores with 1 mm spacing) coated with electrospun fibers containing 9.1 wt% fluorodecyl POSS used for oil-water separation. Octane droplets (colored with oil red O dye) easily pass through the membrane whereas water droplets (dyed with methylene blue) bead up on the surface. This image relates to an article that appeared in the Dec. 7, 2007 issue of the journal Science, published by AAAS. The study, by Dr. Anish Tuteja and colleagues at Massachusetts Institute of Technology in Cambridge, MA, was titled "Designing Superoleophobic Surfaces."
