Abstract

A polyamide(PA 6)/carbon filler composite using a carbon filler masterbatch (MB) was prepared and its melting and crystallization behaviors were examined. MB was applied for carbon black (CB) and graphene nanoplates (GNP), and Avrami analysis was performed for the PA 6/carbon filler composite. As a result of Avrami index analysis, it was confirmed that the crystal growth process changed from a sphere for PA 6 to a disc shape for the composite. The PA 6/carbon filler composite showed two crystallization peaks, which were interpreted to be due to a new crystallization process at the carbon filler interface rather than a change in crystal structure. The crystal size of the PA 6/carbon filler composite to which MB was applied decreased and the time to reach the maximum relative crystallinity increased. This can be explained because carbon filler affects crystallization kinetics when used as MB.


탄소필러 마스터배치(master batch, MB)가 사용된 PA 6/탄소필러 복합체를 제조하여 용융 거동과 결정화 거동을 고찰하였다. 카본블랙(CB)과 그래핀나노플레이트(GNP)에 대해 MB가 적용되었으며 PA 6/탄소필러 복합체에 대해 Avrami 분석을 수행하였다. Avrami 지수 분석결과 결정 성장과정이 PA 6의 경우 구형에서 복합체에 대해서는 원반형으로 변화되는 것이 확인되었다. PA 6/탄소필러 복합체의 결정화 피크는 두개를 보여 주었는데, 이는 결정구조의 변화보다는 탄소필러 계면에서의 새로운 결정화 과정에 기인한 것으로 해석되었다. MB가 적용된 PA 6/탄소필러 복합체의 결정크기가 감소하고 상대결정화도 최대값 도달 시간이 증가하였는데, 이는 탄소필러가 MB로 사용될 때 결정화 속도론에 영향을 주기 때문으로 설명할 수 있다.
