Abstract
Provided is a method for stably storing a nanocarbon dispersion liquid comprising a surfactant for a long period of time. One aspect of the present invention relates to a method for storing a nanocarbon dispersion liquid comprising a low-temperature storage step of storing the nanocarbon dispersion liquid at 10° C. or lower and/or a surfactant concentration adjustment step of adjusting a concentration of the surfactant in the nanocarbon dispersion liquid so as to be less than 100 times of a critical micelle concentration and equal to or more than the critical micelle concentration.
