Novel piezoelectric sensor and nanogenerator based on nanofiber web prepared through electrospinning the blend solution of PVDF and partially sulfonated polyarylene-based polymers

摘要

The present invention relates to a piezoelectric sensor fabricated by electrospinning a mixed solution of PVDF and partial sulfonated PPS and a new nanofiber web having a nano-power generation function, and more specifically to a polyvinylidene difluoride (polyvinylidene difluoride) The present invention relates to a method for preparing a nanofiber web having piezoelectricity by dissolving sulfonated polyphenylene sulfide in a solvent and electrospinning the same. According to the present invention, unlike the conventional method of producing a high-molecular piezoelectric material, which uses a high-cost material and requires separate elongation and high-voltage processing, a piezoelectric material having excellent piezoelectricity by using only a low- Materials can be manufactured. In addition, since the piezoelectric material manufactured according to the present invention outputs an electric signal as a direct current, there is an advantage that a separate stopper is not required when the piezoelectric material is used as a generator or a piezoelectric sensor.
