Beschreibung
Zusammenfassung:	The present invention relates to a reduced graphene oxide/ polyvinylidene difluoride (PVDF) composite material, a production method thereof, and a temperature and a piezoelectric sensor using the same. More specifically, disclosed is a reduced graphene oxide/PVDF composite material which includes: PVDF; and 0.001-3 wt% of reduced graphene oxide with respect to 100 wt% of the PVDF, wherein the composite material has negative temperature coefficient thermistor (NTC) properties. The composite material can be molded into various shapes, and shows high temperature-variable resistance reduction value, thereby having industrial applicability. 본 발명은 환원된 산화그래핀/PVDF 복합소재, 이의 제조방법 및 이를 이용온도 및 압전 센서에 관한 것으로, 보다 구체적으로는 폴리비닐리덴플루오라이드(PVDF); 및 상기 PVDF 100중량% 대비 0.001 내지 3 중량 %의 환원된 산화그래핀을 포함하는 복합소재이고, 상기 복합소재는 부온도계수 써미스터 (negative temperature coefficient thermistor; NTC) 특성을 갖는 것을 특징으로 하는, 환원된 그래핀/PVDF 복합소재가 개시된다. 이러한 본 발명의 복합소재는 다양한 형태로 성형이 가능하고 온도변화에 따른 저항 감소 값이 커서 산업 활용도가 높다.
