Oil/Water Separation Performances of Superhydrophobic and Superoleophilic Sponges

posted on 2014-11-11, 00:00 authored by Qingping Ke, Yangxin Jin, Peng Jiang, Jian YuSuperhydrophobic and superoleophilic
sponges were fabricated by
immersion in an ethanol solution of octadecyltrichlorosilane. The
resulting coating strongly adheres to the sponges after curing at
45 °C for 24 h. Absorption capacities of 42–68 times the
polymerized octadecylsiloxane sponge weight were obtained for toluene,
light petroleum, and methylsilicone oil. These adsorption capacities
were maintained after 50 cycles.
