Embodiment 1
[0064] Example 1 Weigh 475 mg of carbon nanotubes purified by hydrochloric acid, and disperse them in 1 L of deionized water. The dispersant is polyvinylpyrrolidone, and stir for several minutes with a high-shear mixer until the carbon nanotubes form a slurry-like distribution in the dispersion. Weigh 25 mg of graphene oxide, disperse it in 1L of deionized water, and stir it with a high-shear mixer for several minutes until the graphene oxide forms a slurry-like distribution in the dispersion. Mix the dispersion of carbon nanotubes and the dispersion of graphene oxide, and stir them with a mixer for several minutes to mix them evenly to form a stable dispersion. Spread the cellulose filter paper on the bottom of a Buchner funnel with a diameter of 25 cm, and filter it with a vacuum pump, so that the mixed dispersion of carbon nanotubes and graphene oxide is evenly deposited on the filter paper, and when it is semi-dry, the graphene oxide / carbon nanotubes The composite nanoca...
Embodiment 2
[0065] Example 2 Weighed 450 mg of carbon nanotubes purified by hydrochloric acid, weighed 50 mg of graphene oxide, and prepared composite nanocarbon paper with a graphene oxide content of 10% by the same method as in Example 1. Its cross-sectional structure is as Figure 3b shown.
Embodiment 3
[0066] Example 3 Weighed 425 mg of carbon nanotubes purified by hydrochloric acid, weighed 75 mg of graphene oxide, and prepared composite nanocarbon paper with a graphene oxide content of 15% by the same method as in Example 1. Its structure is as Figure 3c shown.
