Outline of Final Research Achievements

An organic pyroelectric material was tried to be controlled its molecular orientation and film structure to improve the infrared and the pressure sensors. The organic pyroelectric materials used in this study were polyurea and urea oligomer. The urea oligomer could be deposited under the vacuum, moreover their films showed the high crystallinity, molecular orientation, thermal protectivity, surface hardness, and low dielectric constant. In parallel, the silk fibroin films were fabricated and controlled the structure to the beta sheet, which was known the advantage of sensor application. We revealed the relationship between the molecular structure and electric properties.

Academic Significance and Societal Importance of the Research Achievements

生活環境に無数のセンサが配置される生活が実現しつつある中、有機焦電材料は鉛フリー、レアメタルフリー、フレキシブル等の特長から様々な取付箇所に対応可能である。本成果を応用することで、従来材料の課題であった耐熱性・耐久性を払拭できる可能性が示された。また、尿素材料と同様に極性分子であるシルクフィブロインに関して、従来の繊維状ではなく薄膜での利用を可能とし、膜内分子構造を制御した。これにより、シルクフィブロイン薄膜の物理化学的構造と電気機能性に関する知見を得た。
