Title:
ELECTRET SHEET
Document Type and Number:
Japanese Patent JP2013245261
Kind Code:
A
Abstract:
To provide an electret sheet having high piezoelectricity.
An electret sheet can trap charges at an interface between a synthetic resin particle and a phthalocyanine compound and can exhibit excellent piezoelectricity by implanting charges into a synthetic resin sheet including a synthetic resin and the phthalocyanine compound to electrify the synthetic resin sheet. When an external force is applied to the electret sheet, positive charges and negative charges collected at the interface between the synthetic resin and the phthalocyanine compound are relatively displaced, and a satisfactory electric response can be caused according to this relative displacement.
