Abstract
A method for producing a sheet having nanofibers that contain a piezoelectric polymer material. The method including dissolving a piezoelectric polymer material into a solvent so as to prepare a spinning solution; preheating a target board before nanofibers are formed by electrospinning the spinning solution; and, after the heating of the target board, receiving the nanofibers formed by electrospinning onto the heated target board so as to form the nanofibers into a sheet on the heated target board.
Claims8
A sheet comprising nanofibers, the nanofibers comprising a high molecular weight piezoelectric material with a degree of crystallinity of 50% or more, wherein a fiber diameter of the nanofibers contained in the sheet is 400 nm to 600 nm, and wherein the sheet has orientation in which an orientation angle of a minor axis direction is ±45° or less in an elliptical approximation.
