Abstract:
1. A process for producing a fluorinated nanodiamond dispersion liquid, comprising; a purification step of mixing a fluorinated nanodiamond with an alcohol having a carbon number of 4 or fewer, then conducting an ultrasonic treatment to produce a suspension, and subjecting the obtained suspension to a classification treatment by centrifugation to produce a dispersion liquid of fluorinated nanodiamond; a drying step to prepare a dry fluorinated nanodiamond by removing the alcohol from the dispersion liquid of fluorinated nanodiamond that is obtained by the purification step; and a redispersion step to prepare the fluorinated nanodiamond dispersion liquid by mixing the dry fluorinated nanodiamond that is obtained by the drying step, with an aprotic polar solvent and then conducting an ultrasonic treatment.
