Aluminum-exfoliated Graphite Nanoplatelet 혼성 입자를 이용한 Polycarbonate 복합체의 기계적 성질과 열전도도

국문 초록 (Abstract)

본 연구에서는 폴리카보네이트/알루미늄-팽창흑연 나노판(PC/Al-xGnP) 복합체가 제조하였다. PC 복합체 제조에 앞서 두 종류의 Al-xGnP 혼성 입자가 제조되었는데 하나는 xGnP가 Al-flake에 완전 삽입된 입자이고 다른 하나는 부분 삽입된 입자이다. 두 종류의 혼성 입자의 삽입 정도는 투과 전자 현미경으로 확인하였다. 부분 삽입된 PC/Al-xGnP 복합체의 열전도도는 완전 삽입된 PC/Al-xGnP 복합체보다 모든 함량에서 높게 관찰되었다. 반면에, 기계적인 성질은 완전 삽입된 PC/Al-xGnP 복합체가 부분 삽입된 PC/Al-xGnP 복합체보다 우수하였다.

다국어 초록 (Multilingual Abstract)

Polycarbonate/aluminum-exfoliated graphite nanoplatelets (PC/Al-xGnP) composites were prepared. Prior to the preparation of the composite, two types of Al-xGnP hybrid powder were prepared, one is fully inserted xGnP and the other is partially inserted xGnP in Al-flakes. TEM images of hybrid powder showed the partially and fully inserted xGnP in Al-flakes. The thermal conductivity of partially inserted PC/Al-xGnP composite was higher than that of fully inserted PC/Al-xGnP composite at the same filler concentration. On the other hand, the fully inserted PC/Al-xGnP composite was superior to the partially inserted PC/Al-xGnP composite in terms of mechanical properties.
