Fig. 3From: Preparation of a new superhydrophobic/superoleophilic corn straw fiber used as an oil absorbent for selective absorption of oil from waterImages of a water droplet (a) and an oil droplet on raw corn straw fiber (b); a water droplet (c) and an oil droplet (d) on prepared superhydrophobic/superoleophilic corn straw fiber. Compared to raw corn straw fiber, the resulting corn straw fiber indicates its superior superhydrophobicityBack to article page
