Document Type and Number:
Japanese Patent JP5493856
Kind Code:
B2
Abstract:
An organic piezoelectric film that is formed from, as raw materials, at least one type of diamine compound and at least one type of compound having two or more carbonyl or thiocarbonyl groups, and that excels in piezoelectricity and is easily formed (produced) at low cost; and a method of forming the organic piezoelectric film. The organic piezoelectric film is one formed by thermal polymerization and polarization treatment of, as raw materials, at least one type of diamine compound and at least one type of compound having two or more carbonyl or thiocarbonyl groups. The organic piezoelectric film is characterized in that it is formed by applying an equivalent mixing solution of the raw materials on a substrate and causing the thermal polymerization and polarization treatment thereof to simultaneously progress.
