specific Embodiment approach 1

[0023] Specific embodiment one: the preparation method of a kind of bacterial cellulose / polyaniline / graphene membrane material of present embodiment is carried out as follows:

[0024] 1. Cut the bacterial cellulose into pieces, soak it in deionized water and ultrasonically wash it, then place it in deionized water, stir to make it evenly dispersed, and then transfer it to a homogenizer for stirring to obtain a bacterial cellulose slurry;

[0025] Two, add surfactant in the graphene of acidification, then be dispersed in the hydrochloric acid solution that concentration is 1mol / L, add aniline monomer again, stir to make aniline monomer and graphene disperse evenly, obtain mixed solution A;

[0026] 3. Mix the oxidizing agent with a hydrochloric acid solution with a concentration of 1mol / L to obtain a mixed solution B; add the mixed solution B dropwise to the mixed solution A at a rate of 0.5 drops to 60 drops / s, and in situ oxidative polymerization to form a polymer Aniline / gr...

specific Embodiment approach 2

[0033] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the bacterial cellulose is bacterial cellulose leftovers. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0034] Specific embodiment 3: The difference between this embodiment and specific embodiment 1 or 2 is that the condition of the ultrasonic washing described in step 1 is 10 hours of ultrasonic time, and the deionized water is replaced every hour. Others are the same as in the first or second embodiment.

Abstract

The invention discloses a preparation method of a bacterial cellulose / polyaniline / graphene film material and application thereof and relates to the preparation method of the film material and application thereof. The invention aims at solving the problems of complex preparation process, high cost and poor stability and mechanical property of an existing flexible electrode material. The preparation method disclosed by the invention comprises the following steps: preparing bacterial cellulose pulp; preparing a polyaniline-graphene compound material solution, carrying out vacuum filtration on the bacterial cellulose to form a film, then adding the polyaniline-graphene compound material solution, continuously carrying out filtration and drying, and preparing the bacterial cellulose / polyaniline / graphene film material for the application in a supercapacitor. The bacterial cellulose / polyaniline / graphene film material has the advantages that large-scale production can be achieved; the preparation process is simple; the cost is low; the stability and the mechanical property of the conducting film material are good, and the prepared supercapacitor has good capacitive character. The invention belongs to the technical field of nano materials.

Description

technical field [0001] The invention relates to a preparation method and application of a membrane material. Background technique [0002] Traditional energy sources are increasingly depleted, stimulating people to look for alternative energy sources and efficient energy storage devices, and supercapacitors have high power density and high energy density, and are used in hybrid electric vehicles, electric vehicles, portable electronic devices and other important fields have always been favored by people. [0003] In today's society, the demand for energy storage of flexible and bendable devices is rapidly increasing, and people urgently need to develop the next generation of cheap, soft and bendable supercapacitors, and electrode materials are the most important components. However, the preparation process of existing flexible electrode materials is complicated, the cost is high, and they do not have good stability and mechanical properties. Therefore, it is particularly i...
