AB  - The formation of liquid crystal (LC) phases in graphene oxide (GO) aqueous 
      solution is utilized to develop high-performance supercapacitors. To investigate 
      the effect of LC formation on the properties of subsequently reduced GO (rGO), we 
      compare films prepared through blade-coating of viscous LC-GO solution and 
      ultrasonic spray-coating of diluted GO aqueous dispersion. After hydrothermal 
      reduction under identical conditions, the films show different morphology, oxygen 
      content, and specific capacitance. Trapped water in the LC GO film plays a role 
      in preventing restacking of sheets and facilitating the removal of oxygenated 
      groups during the reduction process. In device architectures with either liquid 
      or polymer electrolyte, the specific capacitance of the blade-coated film is 
      twice as high as that of the spray-coated one. For a blade-coated film with mass 
      loading of 0.115 mg/cm(2), the specific capacitance reaches 286 F/g in aqueous 
      electrolyte and 263 F/g in gelled electrolyte, respectively. This study suggests 
      a route to pilot-scale production of high-performance graphene supercapacitors 
      through blade-coated LC-GO films.
