POROUS RESIN SHEET FOR PIEZOELECTRIC/PYROELECTRIC ELEMENT AND METHOD OF PRODUCING THE SAME |
摘要 |
<P>PROBLEM TO BE SOLVED: To provide a porous resin sheet for a piezoelectric/pyroelectric element having a high piezoelectric rate and excellent piezoelectric performance, and to provide a method of producing the same. <P>SOLUTION: In the method of producing a porous resin sheet for a piezoelectric/pyroelectric element including a charging process where the inside of a bubble is charged by performing electron beam irradiation processing or corona discharge processing on a porous resin sheet, the charging process is performed in a state where a cover layer having a capacitance index X of 0.2 or higher is laminated on one or both surfaces of the porous resin sheet. Capacitance index X=(dielectric constant of cover layer ε<SB POS="POST">r</SB>)/(thickness of cover layer d[μm]). <P>COPYRIGHT: (C)2012,JPO&INPIT |
