BLEND ORIENTED FILM OF VINYLIDENE FLUORIDE-TRIFLUOROETHYLENE COPOLYMER AND CARBON NANOTUBE AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a blend film of a P(VDF/TrFE) and a carbon nanotube having high elasticity, excellent transparency and crystal orientation, a high Pr value (residual polarization value) and a high piezoelectric effect and to provide a method for manufacturing the blend film of a P(VDF/TrFE) and a carbon nanotube.

SOLUTION: In the method for manufacturing the blended film of a copolymer of vinylidene fluoride and trifluoroethylene and fullerene, after the copolymer of the vinylidene fluoride and trifluoroethylene, and an MWCNT or an SWCNT are dissolved in a solvent, a film (cast film) obtained by solution casting is stretched and then subjected to heat treatment crystallization.
