Abstract: Proposed is a method for producing a polymeric piezoelectric composite having boron nitride nanotubes (BNNT) dispersed therein, the method including: a solution-providing step for providing a polymeric solution; a dispersing step for dispersing BNNT in the polymeric solution; and an electro spinning step for electro spinning the polymeric solution with BNNT dispersed therein, thereby producing micro- and/or nano fibers based polymeric piezoelectric composites.
