Embodiment 1

[0034] A kind of preparation method of molybdenum trioxide-polypyrrole-polyaniline ternary composite material, concrete steps are:

[0035] 1. Preparation of molybdenum trioxide nanobelts by hydrothermal method:

[0036] Add 1.21g of sodium molybdate and 0.6g of sodium chloride into 60mL of deionized water to obtain a solution, keep stirring for 10 minutes to obtain a uniform dispersion, add 3mol / L hydrochloric acid solution to adjust the pH to 1, transfer to a hydrothermal kettle in an oven The hydrothermal reaction was carried out at 180°C, and the reaction time was 24h. When the reaction kettle was cooled down to room temperature, the obtained dispersion liquid was subjected to suction filtration to separate the light blue precipitate, and the obtained solid was washed with deionized water. Dry in an oven at 60° C. for 24 hours to obtain molybdenum trioxide nanobelts.

[0037] 2. In situ growth of polypyrrole on molybdenum trioxide nanobelts to obtain molybdenum trioxide-p...

Abstract

The invention provides a preparation method of a molybdenum trioxide-polypyrrole-polyaniline ternary composite material. The method comprises the following steps: 1, preparing molybdenum trioxide nanobelts through a hydrothermal technology; 2, carrying out in situ growth of polypyrrole on the molybdenum trioxide nanobelts to obtain a molybdenum trioxide-polypyrrole binary composite material; and 3, carrying out in situ growth of polyaniline on the surface of the molybdenum trioxide-polypyrrole binary composite material used as a template in order to obtain the molybdenum trioxide-polypyrrole-polyaniline ternary composite material. The molybdenum trioxide-polypyrrole-polyaniline ternary composite material prepared in the invention can be used in high-performance super capacitors, lithium ion batteries, solar batteries and other novel energies as an ideal electrode material.

Description

technical field [0001] The invention belongs to the technical field of transition metal oxides-conductive polymer materials, and in particular relates to a method for preparing a molybdenum trioxide-polypyrrole-polyaniline ternary composite material. Background technique [0002] With the increasingly serious energy crisis and environmental problems, the development of clean and sustainable energy has become a hot research field and topic in the world today. Polyaniline has good processability, excellent conductivity, rapid doping-dedoping ability, and high storage capacity, and is considered to be one of the most promising conductive polymers as electrode materials. However, polyaniline is prone to expansion and contraction during the repeated doping / dedoping process, resulting in a decrease in cycle stability, which restricts its practical application. Polypyrrole is easy to synthesize, has controllable morphology, reversible doping / dedoping, is environmentally friendly, ...
