Abstract
Polypropylene (PP)/functionalized multiwalled carbon nanotube (F-MWNT) nanocomposites were prepared by using solution intercalation method with different F-MWNT loads. The PP composite films, which contain dodecanol-MWNT (DDO-MWNT) or dodecylamine-MWNT (DDA-MWNT) as reinforcing additive, were evaluated by thermomechanical properties, morphology, electrical conductivity and gas permeability. The images from electron microscopy (SEM and TEM) showed that F-MWNTs were homogeneously dispersed in PP matrix, while they were agglomerated in some other part. The addition of F-MWNT could improve thermomechanical properties of the films. The maximum enhancement was observed at 2 wt% F-MWNT. DDO-MWNT was more effective than DDA-MWNT for both tensile modulus and optical transparency of the films.

폴리프로필렌(PP)/기능화된 다중벽 탄소나노튜브(F-MWNT)나노복합체를 용액 삽입법을 이용해서 제조하였다. 두 종류의 F-MWNT인 dodecanol-MWNT(DDO-MWNT)와 dodecylamine-MWNT(DDA-MWNT)를 포함하는 PP 복합체 필름의 열적, 기계적 성질, 모폴로지, 전기전도도, 필름의 투명도 및 개스투과도 등을 조사하고 그 물성을 구조가 다른 F-MWNT에 따라 서로 비교하였다. 전자 현미경(SEM과 TEM) 사진을 통하여 일부의 MWNT는 잘 분산이 되었으나 그렇지 않은 부분도 확인하였다. 적은 양의 F-MWNT가 첨가되어도 PP 복합체 필름의 열적ㆍ기계적 물성이 향상되었으며, 2 wt%에서 최대값을 보여주었다. 일반적으로 PP 복합체 필름의 초기 탄성율과 광학 투명도에서 DDO-MWNT가 DDA-MWNT 보다 더 효과적이었다.
