Embodiment 1

[0028] (1) Prepare the electrolyte: weigh 2.225g of dioctyl sodium sulfosuccinate (AOT), add 100ml of deionized water to prepare a 0.05M AOT electrolyte, and stir for 30 minutes with a magnetic stirrer. According to the mass percentage of pyrrole and graphene being 90%: 10%, add 0.038g graphene to the electrolyte solution, and put it aside for 10 minutes to obtain a uniformly dispersed mixed solution.

[0029] (2) Preparation of polypyrrole / graphene composite material: Weigh 0.345g (0.1M) pyrrole monomer into the above mixed solution, and stir magnetically for 10 minutes. The polymerization experiment was carried out in a three-electrode system controlled by an electrochemical workstation, with a stainless steel mesh as the working electrode, a platinum sheet as the counter electrode, and a saturated calomel electrode as the reference electrode. The test temperature was (10°C + 2°C). Using a constant potential method, the polymerization voltage is 1V, and the polymerization t...

Abstract

The invention discloses a method for preparing a polypyrrole / graphene composite film material. The method comprises the steps of: firstly, adding graphene powder and a pyrrole monomer into a dioctyl sodium sulfosuccinate (AOT) water solution with a certain concentration according to a certain proportion, ultrasonically dispersing to obtain uniform electrolyte, and electrically polymerizing on an electroconductive electrode to obtain the polypyrrole / graphene composite film material by adopting an electrochemical method, wherein the experiment is carried out in a tri-electrode system controlledby an electrochemical work station. The method disclosed by the invention has the advantages of simple process, controllable operation flow, short time and low cost, and graphene in the the prepared composite film material is favorably wrapped by a polypyrrole material, and the composite film material can be used as an anti-corrosion material and can also be applied to the fields of electric containers, lithium ion batteries, sensors, electronic devices, fuel batteries and the like.

Description

technical field [0001] The invention relates to a preparation method of a polypyrrole / graphene composite film material, in particular to using a large anionic surfactant—dioctyl sodium sulfosuccinate as an electrolyte to form a polypyrrole / graphene composite film by an electrochemical method material method. Background technique [0002] Conductive polypyrrole has become one of the most promising conductive polymers due to its superior biocompatibility, environmental stability, and ease of preparation, and is widely used in biosensors, supercapacitors, and anti-corrosion materials. In recent years, in order to develop new materials with high specific surface area, electrochemical stability and superior mechanical properties, the study of composites of polypyrrole and other nanomaterials has become a major research hotspot. Graphene is a hexagonal crystal densely packed with carbon atoms in two-dimensional space, which has excellent electrical, thermal and mechanical propert...
