Abstract
PbTiO3/P(VDF/TrFE) 0∼3 composites thin films with 0.10 and 0.13 of ceramic volume fraction factor have been fabricated by two-step spin coating technique and analyzed. 0∼3 connectivity of PbTiO3/P(VDF/TrFE) composites film was observed successfully by SEM micrography. The SEM picture confirmed 0∼3 connectivity. And, in all the properties, 0∼3 PbTiO3/P(VDF/TrFE) composites film was superior to P(VDF/TrFE) copolymer. Therefore, with a good low-dielectric constant and a high pyroelectric coefficient, the composite thin films can be used for a new pyroelectric infrared sensor of higher performance.

두 단계 스핀 코팅 방법을 사용하여 세라믹 체적 분율 0.10과 0.13의 PbTiO3/P(VDF/TrFE) 0~3형 복합재료를 제작하고 분석하였다. 0~3형 PbTiO3/P(VDF/TrFE) 복합재료를 SEM 전자현미경 사진으로 성공적으로 확인할 수 있었다. 이러한 전자현미경 사진을 통하여 복합재료의 0~3형 구조를 재확인하였다. 0~3형 PbTiO3/P(VDF/TrFE) 복합재료는 P(VDF/TrFE) 공중합체보다 센서용 전기적 특성이 우수함을 나타내었다. 그러므로 이러한 낮은 유전상수와 높은 초전계수를 나타내는 0∼3형 PbTiO3/P(VDF/TrFE) 복합재료는 더 높은 성능을 나타낼 수 있는 새로운 초전형 센서 재료로 사용될 수 있다.

Keywords: PbTiO3; P(VDF); P(VDF/TrFE); composites; infrared.
