| titleOfInvention | Preparation method of reduced graphene oxide, hole injection material and preparation method thereof |
| abstract | The invention belongs to the technical field of photoelectric materials, and particularly relates to a preparation method of reduced graphene oxide, a hole injection material and a preparation method of the hole injection material. The preparation method of the reduced graphene oxide comprises the following steps: providing graphene oxide; and dissolving the graphene oxide in hydrogen-rich water, and carrying out first heating treatment in an alkaline environment to obtain a reduced graphene oxide solution. The reduced graphene oxide obtained by the preparation method increases the carrier concentration, reduces the resistivity, and is beneficial to the hole transport of devices, so that a more ideal reduced graphene oxide material with higher hole mobility can be obtained. |
