1Preparation and characterization of colorful graphene oxide papers and flexible N-doping graphene papers for supercapacitor and capacitive deionization显示文摘An efficient method that utilizes simple techniques,easy operation,and low-cost production to create flexible graphene-based materials is a worthy practical challenge.A rapid strategy for preparing flexible,functional graphene oxide(GO)is introduced using GO-ethanol dispersion filtration.The filtration process is highly efficient and drying time is significantly reduced by employing ethanol as solvent,due to the fact that ethanol is a volatile liquid.Freestanding GO papers can be harvested with ultralarge size(700 cm2),color variety,and writable characteristics.After reduction,N-doped graphene(NDG)papers still maintain good foldability with improved electric conductivity and porous structure.When used as an electrode for a supercapacitor,the flexible NDG paper device demonstrates good electrochemical performance even with size expansion and extreme double folding.Moreover,this NDG paper capacitor device shows a good electrosorption performance for capacitive deionization of sulfate and chromate in groundwater system.These flexible GO and NDG papers promise potential to facilitate the production of graphene-based materials for practical applications in energy and environmental related fields.Hao Zhang Aiyang Li Ying Yuan Yuquan Wei Di Zheng Zhuning Geng Haichuan Zhang Guanghe Li Fang Zhang 2020Carbon Energy2020,2,4:0
