Embodiment 1
[0029] Weigh an appropriate amount of aluminum trichloride, add the anhydrous solvent dimethyl sulfoxide (DMSO) dropwise to aluminum trichloride in an ice-water mixed bath with stirring, and heat to trichloride after the addition is complete. Aluminum chloride is completely dissolved, and is made into a 4wt% aluminum chloride solution. Add polyvinyl alcohol to anhydrous dimethyl sulfoxide to form a solution with a concentration of 5 wt %, add carbon nanotubes at a mass ratio of multi-walled carbon nanotubes to polyvinyl alcohol at a ratio of 1:10, and mix thoroughly. The dimethyl sulfoxide solution of polyvinyl alcohol and carbon nanotubes was poured into the solution of aluminum trichloride, and reacted at 70° C. for 24 hours. Pour the reaction solution into a solution of methanol and dilute hydrochloric acid (0.1mol / L) with a mass ratio of 1:2 to precipitate, centrifuge at 13000rpm, separate and dry to obtain polyvinyl alcohol-modified carbon nanotubes , denoted as CNT-g-PV...
Embodiment 2
[0034] Weigh an appropriate amount of aluminum trichloride, add the anhydrous solvent dimethyl sulfoxide (DMSO) dropwise to aluminum trichloride in an ice-water mixed bath with stirring, and heat to trichloride after the addition is complete. Aluminum chloride is completely dissolved to form a 10wt% aluminum chloride solution. Add polyvinyl alcohol to anhydrous dimethyl sulfoxide to form a solution with a concentration of 20wt%, add carbon nanotubes at a mass ratio of 1:20 to multi-walled carbon nanotubes and polyvinyl alcohol, mix thoroughly, and The dimethyl sulfoxide solution of polyvinyl alcohol and carbon nanotubes was poured into the solution of aluminum trichloride, and reacted at 90° C. for 12 hours. Pour the reaction solution into a solution of methanol and dilute hydrochloric acid (0.1mol / L) with a mass ratio of 1:2 to precipitate, centrifuge at 13000rpm, separate and dry to obtain polyvinyl alcohol-modified carbon nanotubes .
