AB  - A new method for transforming common polymers into superhydrophobic conductive 
      surfaces, with both a high static water contact angle (approximately 160 degrees) 
      and a low sliding angle (2.0 degrees-4.5 degrees), and a low sheet resistance on 
      the order of 10(1)-10(3) ohms/sq is presented. A layer of multiwalled carbon 
      nanotubes (MWNTs) is first distributed on the surface of a polymer substrate, 
      then by a single step of pressing, the MWNTs are partially embedded inside the 
      substrate surface and form a superhydrophobic coating with a "carpet-" or 
      "hair"-like morphology. The infiltration of polymer melts into the porous MWNT 
      layer follows Darcy's law, and the pressing time greatly influence the morphology 
      and superhydrophobicity. Moreover, the coating can be electrically heated by 
      20-70 degrees C with a voltage as low as 4-8 V at an electric energy density 
      below 1.6 J/cm(2) and therefore can be used for deicing applications. 
      Hydroxylation and fluoroalkylsilane treatment can greatly improve the stability 
      of the superhydrophobicity of MWNTs. This method is convenient and applicable to 
      a variety of thermoplastic polymers and nonpolymer substrates coated by silicone 
      rubber.
