Abstract
A method for making a carbon nanotube composite film is provided. A PVDF solution is formed by dissolving a PVDF into a first solvent. A number of carbon nanotubes are provided and distributed into the PVDF solution to form a first suspension. The first suspension is transferred into a second solvent to form a second suspension. The second suspension is filtrated to obtain an intermediate, then the intermediate is dried. A solubility of first solvent in the second solvent is greater than a solubility of PVDF in the second solvent.
Claims20
A method for making a carbon nanotube composite, the method comprising the following steps:
- (a) dissolving a poly vinylidene difluoride (PVDF) into a first solvent to form a PVDF solution;
- (b) making a first suspension by distributing a plurality of carbon nanotubes into the PVDF solution;
- (c) forming a second suspension by transferring the first suspension into a second solvent, wherein a solubility of first solvent in the second solvent is greater than a solubility of the PVDF in the second solvent, and a boiling point of the second solvent is lower than a boiling point of the first solvent;
- (d) filtrating the second suspension to obtain an intermediate;
- and
- (e) drying the intermediate.
