Carbon nanotube aqueous phase dispersion method and preparation method of aqueous carbon nanotube composite film slurry

The invention provides a carbon nano tube water phase dispersion method and a preparation method of water-based carbon nano tube composite film slurry by taking development of a carbon nano tube film as an application basis. The strong oxidizing property of hydrogen peroxide is utilized to remove a carbon by-product wrapping a metal catalyst, the carbon nanotubes are subjected to oxidation modification, and then the oxidation degree of hydrogen peroxide is regulated and controlled through ammonia water. According to the method, the carbon nanotubes can be dispersed on the premise that the high performance of the carbon nanotubes is not affected, and the provided oxidation modification method is simple, efficient and easy to operate and has universality. The required temperature is low, and the method can be carried out at normal temperature; and meanwhile, no wastewater is generated in the reacted purified suspension, a filtering and cleaning process and wastewater discharge are not needed, the production cos
