摘要
Disclosed are a nanofiber web piezoelectric material and a method of producing the same, wherein a spinning solution of polylactic acid (PLA) in a solvent is electrospun, yielding a nanofiber web, thereby exhibiting piezoelectric properties without additional drawing. This piezoelectric material is remarkably cost-effective, can exhibit superior piezoelectric properties, can be used to manufacture inexpensive piezoelectric products, and obviates any additional drawing because the PLA chain is drawn during electrospinning. The drawing force induced by a high electric field between the needle and the collector enables the formation of 31 helical β-crystal chains in a uniaxial direction even without any other drawing process. This PLA nanofiber web is very thin and flexible, the PLA chains are effectively aligned in an electric field direction due to the high DC voltage used for electrospinning, and helical β conformation is easily formed in a single process using electrospinning.
