Abstract
A method for transferring a carbon nanotubes aqueous phase dispersion into an organic phase dispersion includes: providing the carbon nanotubes aqueous dispersion; mixing the carbon nanotubes aqueous dispersion with a first solvent to obtain a first suspension, where the first solvent includes a hydrophilic organic solvent; mixing the first suspension with a second solvent to form two stratified phases, allow to obtain a second suspension, where the second solvent includes a hydrophobic organic solvent; mixing the second suspension with a third solvent to obtain a third suspension; and subjecting the second suspension or the third suspension to dispersion treatment to obtain a carbon nanotubes organic dispersion, thereby realizing solvent transfer of the carbon nanotubes dispersion from aqueous to organic phase. The method can transfer the carbon nanotubes aqueous dispersion into the organic dispersion, and the transfer efficiency is 70%-95%.
