Document Type and Number:
WIPO Patent Application WO/2021/246418
Kind Code:
A1
Abstract:
Provided is a method for producing a sheet having nanofibers that contain a piezoelectric polymer material, said method including the following steps (a) to (c): (a) a step for dissolving a piezoelectric polymer material into a solvent so as to prepare a spinning solution including the piezoelectric polymer material; (b) a step for preheating a target plate before nanofibers are formed by electrospinning the spinning solution, said target plate being for receiving the nanofibers; and (c) a step for receiving the nanofibers formed by electrospinning onto the target plate, so as to form the nanofibers into a sheet on the target plate. Also provided is a sheet produced by said production method.
