Method for making carbon nanotube composite films

摘要

A method for making a carbon nanotube composite film is provided. A PVDF is dissolved into a first solvent to form a PVDF solution. A number of magnetic particles is dispersed into the PVDF solution to form a suspension. A carbon nanotube film is immersed into the suspension and then transferred into a second solvent. The carbon nanotube film structure is transferred from the second solvent and dried to form the carbon nanotube composite film.

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.
