Abstract

The invention relates to a preparation method of a reduction-oxidation oxidized graphene vinyl photoelectric active composite material and relates to a preparation method of a photoelectric active composite material. The preparation method of the reduction-oxidation oxidized graphene vinyl photoelectric active composite material aims at solving the problems that oxidized graphene functionalization degree is low, reaction conditions are harsh when thionyl chloride is taken as a catalyst and a technology is complex and environmental friendliness is not realized in a production process of the existing graphene functional material. The preparation method of the reduction-oxidation oxidized graphene vinyl photoelectric active composite material comprises the following steps: firstly, preparing a DMF (dimethyl formamide) solution containing oxidized graphene, a coupling agent and a photoactive material; secondly, sequentially adding the DMF solution containing the coupling agent and the photoactive material into the DMF solution containing oxidized graphene for carrying out a compounding reaction; thirdly, transferring the mixed solution obtained through reaction into a high pressure reactor provided with a polytetrafluoroethylene liner for carrying out a reduction reaction; fourthly, after reaction is finished, carrying out suction filtration on solid-liquid mixture, eluting solid with DMF and ethyl alcohol, and drying, so that the reduction-oxidation oxidized graphene vinyl photoelectric active composite material is obtained. The preparation method of the reduction-oxidation oxidized graphene vinyl photoelectric active composite material is applicable to preparation of the reduction-oxidation oxidized graphene vinyl photoelectric active composite material.

Description

technical field [0001] The invention relates to a preparation method of a photoelectric active composite material. Background technique [0002] Because of its unique atomic structure, graphene has special physical and chemical properties such as excellent optics, electricity, heat, large specific surface area, and dipole field effect, and it is used in many fields such as photoelectric conversion functional materials, biosensors, and new composite materials. It has very important research and application value. However, pure graphene is almost insoluble in any solvent due to the van der Waals force between the sheets and the strong π-π stacking interaction and its own insolubility. This greatly hinders the processability and modifiability of graphene, thus limiting the development and application of graphene functional materials. At present, using graphene oxide as raw material to prepare graphene analogs through reduction is considered to be a feasible technology for ind...
