Beschreibung
Zusammenfassung:	Disclosed are a polyimide nanocomposite having a polyimide and a product wherein a defect of a reduced graphene oxide functionalized with at least one selected from a ring compound containing a hetero ring and a hetero atom is healed, a manufacturing method thereof, and a composite membrane having the polyimide nanocomposite. The polyimide nanocomposite of the present invention and a composite film having the same may contain a polyimide and a healed product of the surface of the functionalized reduced graphene oxide to improve dispersibility and improve thermal stability and mechanical properties. 헤테로고리 및 헤테로 원자를 포함하는 고리 화합물 중에서 선택된 하나 이상으로 기능화된 환원 그래핀 옥사이드의 결함이 치유된 생성물 및 폴리이미드를 포함하는 폴리이미드 나노복합체, 그 제조방법 및 상기 폴리이미드 나노복합체를 포함하는 복합막이 제시된다. 본 발명의 폴리이미드 나노복합체 및 이를 포함한 복합막은 기능화된 환원 그래핀 옥사이드의 표면의 결함이 치유된 생성물과 폴리이미드를 함유하여 분산성이 개선됨과 동시에 열적 안정성과 기계적 특성이 향상될 수 있다.
