Embodiment 1
[0032](1) Acidification and dispersion treatment of carbon nanotubes: First, 10 g of carbon nanotube raw materials were weighed and put into a planetary ball mill, and ball milled at a speed of 200 rpm for 40 minutes. Soak the milled carbon nanotubes in 1% hydrofluoric acid for 24 hours. The carbon nanotubes were washed twice with deionized water, and then added to a mixed acid of concentrated sulfuric acid and concentrated nitric acid (volume ratio: 3:1) for reflux reaction for 1 h. The treated carbon nanotubes are washed with deionized water until the pH value is 5, and stored in deionized water for later use;
[0033] (2) Preparation of chitosan solution: Weigh 10g of chitosan powder and dissolve it in 490g of 1% acetic acid solution at room temperature. The sugar is completely dissolved in acetic acid, filtered to remove impurities and stored for later use;
[0034] (3) Preparation of spherical solution: add a certain amount of carbon nanotubes treated in step (1) to the...
Embodiment 2
[0041] (1) Acidification and dispersion treatment of carbon nanotubes: First, 10 g of carbon nanotube raw materials were weighed and put into a planetary ball mill, and ball milled at a speed of 1000 rpm for 20 minutes. Soak the milled carbon nanotubes in 1% hydrofluoric acid for 24 hours. Then, the carbon nanotubes were washed twice with deionized water, and then added to a mixed acid of concentrated sulfuric acid and concentrated nitric acid (volume ratio: 3:1) for reflux reaction for 5 hours. The treated carbon nanotubes are washed with deionized water until the pH value is 6.9, and stored in deionized water containing surfactant sodium lauryl sulfate for later use;
[0042] (2) Preparation of chitosan solution: Weigh 2.5g of chitosan powder and dissolve it in 39.2g of 5% acetic acid solution at room temperature. The final content of chitosan after dissolution is 6wt%. Chitosan is completely soluble in acetic acid, filtered to remove impurities and stored for later use;
