Abstract

The invention discloses a high-concentration carbon nanotube slurry and a preparation method thereof, and solves the technical problem of poor stability of the carbon nanotube slurry in a water environment, the preparation method comprises the following steps: 1) mixing carbon nanotube powder and ionic liquid crystal in a mass ratio of (1: 1)-(5: 1), adding the mixture into deionized water, and fully stirring and uniformly mixing to obtain a mixed solution; 2) putting the mixed solution into a reaction kettle, and carrying out hydrothermal reaction at 150-250 DEG C; 3) taking out a product after the hydrothermal reaction to obtain high-concentration carbon nanotube slurry; the prepared high-concentration carbon nanotube slurry is high in concentration and good in dispersity, can be stably stored for more than 6 months for a long time under the condition of normal temperature, and has relatively high application value.

Description

technical field [0001] The invention relates to the technical field of carbon nanotube slurry preparation, in particular to a high-concentration carbon nanotube slurry and a preparation method thereof. Background technique [0002] Carbon nanotubes are seamless concentric nanoscale tube structures formed by curling graphite sheets, and hemispherical large fullerene molecules formed by five-membered rings and seven-membered rings seal both ends, in which carbon is sp 2 bonded by hybridization. According to the number of layers of graphite sheets in the tube, it can be divided into single-walled carbon nanotubes and multi-walled carbon nanotubes. The extremely high aspect ratio and super strong mechanical properties make carbon nanotubes a one-dimensional nanomaterial with high application potential. Its applications have involved nanoelectronic devices, catalyst supports, electrochemical materials, hydrogen storage materials and composite material enhancements. In many ways...
