Abstract:
1. A method for making a carbon nanotube composite film comprising the following steps: (a) dissolving poly vinylidene difluoride (PVDF) powders into a first solvent to form a PVDF solution; (b) forming a suspension by dispersing a plurality of magnetic particles into the PVDF solution; (c) immersing a carbon nanotube film structure into the suspension; (d) transferring the carbon nanotube film structure into a second solvent; wherein a solubility of first solvent in the second solvent is greater than a solubility of PVDF in the second solvent, and a boiling point of the second solvent is lower than a boiling point of first solvent; and (e) removing the carbon nanotube film structure from the second solvent and drying the carbon nanotube film structure.
