AB  - Graphene oxide (GO) sheets can form liquid crystals (LCs) in their aqueous 
      dispersions that are more viscous with a stronger LC feature. In this work we 
      combine the viscous LC-GO solution with the blade-coating technique to make GO 
      films, for constructing graphene-based supercapacitors in a scalable way. Reduced 
      GO (rGO) films are prepared by wet chemical methods, using either hydrazine (HZ) 
      or hydroiodic acid (HI). Solid-state supercapacitors with rGO films as electrodes 
      and highly conductive carbon nanotube films as current collectors are fabricated 
      and the capacitive properties of different rGO films are compared. It is found 
      that the HZ-rGO film is superior to the HI-rGO film in achieving high 
      capacitance, owing to the 3D structure of graphene sheets in the electrode. 
      Compared to gelled electrolyte, the use of liquid electrolyte (H2SO4) can further 
      increase the capacitance to 265 F per gram (corresponding to 52 mF per cm(2)) of 
      the HZ-rGO film.
