Embodiment 1

[0020] (1) Measure 50mL of concentrated hydrochloric acid, weigh 3.48g of ammonium persulfate and dissolve it in an appropriate amount of water to make the volume of the whole system 300mL, that is, the concentration of hydrochloric acid is 2moL / L. After completely dissolving, pour it into a three-necked bottle, add 1.5g of bamboo charcoal, Stir for 15 minutes, so that the bamboo charcoal can be evenly dispersed in the system, and place the three-necked bottle under an ice bath.

[0021] (2) Get a small beaker, take by weighing the mixed solution of 1g aniline, 7g cyclohexane, 7g n-amyl alcohol in fume hood, the mass ratio of bamboo charcoal and aniline this moment is 3: 2, the mole of ammonium persulfate and aniline The ratio is 1.5:1, shake gently to mix the solution evenly, then pour it into a constant pressure dropping funnel, and control the titration speed so that it drops into a three-necked flask within 30 minutes. The temperature was controlled at 0°C, and the dynamic...

Embodiment 2

[0025] The operation method is the same as Example 1, except that the acid consumption is 25mL, that is, the system acid concentration is 1moL / L; the bamboo charcoal quality is 4g, and the mass ratio of bamboo charcoal and monomer aniline is 4: 1; the ammonium persulfate consumption is 2.32 g, the molar ratio of ammonium persulfate and aniline is 1.5:1.

[0026] Depend on figure 2 It can be seen from the DSC curve that there is a relatively obvious exothermic peak around 360°C, which is the temperature at which polyaniline in the composite material begins to decompose. It can be seen that the thermal performance of the composite material is excellent.

Embodiment 3

[0028] The operation method is the same as in Example 1, except that the acid consumption is 25mL, that is, the system acid concentration is 1moL / L, and the ammonium persulfate consumption is 2.32g, that is, the molar ratio of ammonium persulfate and aniline is 1:1.

[0029] Depend on image 3 It can be seen from the charge-discharge curve of the bamboo charcoal that the curve is a relatively symmetrical triangle, which belongs to an electric double layer capacitor. From the charge-discharge curve of the composite material, it can be seen that there is a pseudocapacitance, and the charge-discharge time of the composite material is two times that of bamboo charcoal. times, that is, its capacitance is much higher than that of the original bamboo charcoal material, indicating that the composite material has greater advantages than the single material in terms of electrochemical performance.

Description

Technical field: [0001] The invention relates to a method for preparing composite materials by using biomass raw materials and aniline, in particular to a method for preparing composite materials by using bamboo charcoal and aniline, and belongs to the field of capacitor materials. Background technique: [0002] Since the beginning of the 21st century, natural mineral energy such as coal and petroleum and chemical raw materials have become increasingly scarce, and industrial pollution and environmental degradation have attracted more and more attention. Energy and sustainable development have become the focus of attention. Finding renewable resources and taking the road of sustainable development have been put on the agenda. With the increasing environmental pollution and decreasing energy resources, the development of new carbon materials based on plant biomass has attracted extensive attention. At present, the research on biochar materials is more concentrated on wood, r...
