| titleOfInvention | High-density aza-graphene film and preparation method thereof |
| abstract | The invention discloses a high-density aza-graphene film and a preparation method thereofThe nitrogen of the graphene film is doped in a pyrrole nitrogen form, the doping concentration is 7.88-7.94%, and the density is 1.69-1.72 gcm ‑3 . The preparation method comprises the following steps: dispersing graphene oxide in a solution containing a large amount of ions (NH) 4 + ，HCO 3 ‑ Etc.) at an appropriate concentration, the graphene sheets are crosslinked into a hydrogel film. And (3) carrying out hydrothermal treatment on the hydrogel film in the same water bath, drying, reducing the hydrogel film into a conductive black film, and collecting the conductive black film by a rewinding machine. The graphene film has the characteristics of high density and high nitrogen doping. The graphene film is used as an electrode material, and the specific mass capacity can reach 262F g ‑1 And the method has application prospect in the field of light electric vehicles and portable electronic devices. |
