Method for producing carbon nanotube dispersion liquid, method for producing composite material composition, method for producing composite material, composite material, and composite-material shaped product
Provided is a method for efficiently producing a carbon nanotube dispersion liquid in which less-damaged carbon nanotubes are highly dispersed. The method for producing a carbon nanotube dispersion liquid includes: (A) obtaining a carbon nanotube dispersion liquid by applying a shear force to a coarse dispersion liquid that includes carbon nanotubes having a specific surface area of 600 m2/g or more to whereby disperse the carbon nanotubes, wherein the step (A) includes at least one of applying a back pressure to the carbon nanotube dispersion liquid and cooling the carbon nanotube dispersion liquid.
