AB  - To address the debates on whether superhydrophobic coatings can reduce fluid drag 
      for underwater motions, we have achieved an underwater drag-reducing effect of 
      large superhydrophobic submarine models with a feature size of 3.5 cm x 3.7 cm x 
      33.0 cm through sailing experiments of submarine models, modified with and 
      without superhydrophobic surface under similar power supply and experimental 
      conditions. The drag reduction rate reached as high as 15%. The fabrication of 
      superhydrophobic coatings on a large area of submarine model surfaces was 
      realized by immobilizing hydrophobic copper particles onto a precross-linked 
      polydimethylsiloxane (PDMS) surface. The pre-cross-linking time was optimized at 
      20 min to obtain good superhydrophobicity for the underwater drag reduction 
      effect by investigating the effect of pre-cross-linking on surface wettability 
      and water adhesive property. We do believe that superhydrophobic coatings may 
      provide a promising application in the field of drag-reducing of vehicle motions 
      on or under the water surface.
