The present invention provides polyvinylidene fluoride (PVDF) and carbon nanotubes, and provides a method for producing nanofiber membranes and nanofiber membranes in which the polyvinylidene fluoride (PVDF) and carbon nanotubes are electrospun. According to the nanofiber membrane of the present invention, it is possible to exhibit excellent mechanical behavior due to high β crystal content of 90% or more, residual polarization value of 60 mC / m 2 , and piezoelectricity. |
