      Superhydrophobic Sponge for Efficient Oil/Water Separation.

AB  - The exploration of nonhazardous nanoparticles to fabricate a template-driven 
      superhydrophobic surface is of great ecological importance for oil/water 
      separation in practice. In this work, nano-hydroxyapatite (nano-HAp) with good 
      biocompatibility was easily developed from discarded oyster shells and well 
      incorporated with polydimethylsiloxane (PDMS) to create a superhydrophobic 
      surface on a polyurethane (PU) sponge using a facile solution-immersion method. 
      The obtained nano-HAp coated PU (nano-HAp/PU) sponge exhibited both excellent 
      oil/water selectivity with water contact angles of over 150 degrees  and higher 
      absorption capacity for various organic solvents and oils than the original PU 
      sponge, which can be assigned to the nano-HAp coating surface with rough 
      microstructures. Moreover, the superhydrophobic nano-HAp/PU sponge was found to 
      be mechanically stable with no obvious decrease of oil recovery capacity from 
      water in 10 cycles. This work presented that the oyster shell could be a 
      promising alternative to superhydrophobic coatings, which was not only beneficial 
      to oil-containing wastewater treatment, but also favorable for sustainable 
      aquaculture.
