Description

technical field [0001] The invention relates to a composite material of carbon nanotube and poly-Schiff base, a preparation method and application thereof. Background technique [0002] Since carbon nanotubes were discovered by Japanese scientist Iijima in 1991, they have attracted widespread attention due to their unique structure, chemical properties, thermal properties and electrical properties. Its applications have been involved in many aspects such as nanoelectronic devices, catalyst supports, hydrogen storage materials and composite materials. While the structure of carbon nanotubes endows it with many superior properties, it also determines its limitations in application. Due to the large π bond on the surface of carbon nanotubes, the surface is neither hydrophilic nor lipophilic, which makes it difficult for carbon nanotubes to disperse and dissolve in various solvents, insoluble in various solvents and difficult to operate and control The characteristics largely ...
