Embodiment 1
[0044] The concrete steps of preparation are:
[0045] Step 1, first mix sulfuric acid ≥ 96wt% and nitric acid ≥ 63wt% according to the weight ratio of 1:1 to obtain mixed acid. According to the weight ratio of 1:10, the carbon nanotubes were placed in a mixed acid at 50°C and stirred for 12 hours, and the reaction solution was sequentially subjected to solid-liquid separation, washing and drying; wherein the carbon nanotubes were multi-wall For carbon nanotubes, the solid-liquid separation treatment is filtration, the washing treatment is to use deionized water to wash and filter the solid matter until the washing liquid is neutral, and the drying treatment is to dry the washed solid matter at 50°C for 48 hours to obtain purified carbon nanotube.
[0046] Step 2, first add the purified carbon nanotubes to a 10wt% surface modifier solution, stir and react at 70°C for 37h and then dry; wherein, the weight of the purified carbon nanotubes and the surface modifier in the surface...

[0052] The concrete steps of preparation are:
[0053] Step 1, first mix sulfuric acid ≥ 96wt% and nitric acid ≥ 63wt% according to the weight ratio of 1:2 to obtain the mixed acid. According to the weight ratio of 3:10, the carbon nanotubes were placed in a mixed acid at 60°C for 10 hours of stirring reaction, and the reaction solution was sequentially subjected to solid-liquid separation, washing and drying; wherein the carbon nanotubes were multi-walled For carbon nanotubes, the solid-liquid separation process is filtration, the washing process is to use deionized water to wash and filter the solid matter until the washing liquid is neutral, and the drying process is to dry the washed solid matter at 60°C for 48 hours to obtain purified carbon nanotube.
[0054] Step 2, first add the purified carbon nanotubes to a 30wt% surface modifier solution, and then dry them after stirring and reacting for 35 hours at 80°C; wherein, the weight of the purified carbon nanotubes and the...
