A nylon 6/carbon filler composite mixed with nylon 6 and carbon filler was manufactured using a masterbatch (MB), and the influence of MB on surface resistance and tensile properties was examined. Carbon black (CB), carbon nanotubes (CNT), and graphene nanoplates (GNP) were used as carbon fillers. The thermal properties of the nylon 6/carbon filler composite were measured using differential scanning calorimetry (DSC), and the crystallization temperature showed a large increase, but the melting temperature did not show a significant change. The results of crystal structure analysis by X-ray diffraction (XRD) showed that the a-type crystal structure was dominant in the case of nylon 6/carbon filler composite. The power law index (n) and phase angle of the nylon 6/carbon filler composite to which MB was applied decreased, and this can be explained as indirect evidence that the dispersibility of the carbon filler is improved when MB is applied.

나일론 6에 탄소필러가 혼합된 나일론 6/탄소필러 복합체를 마스터배치(master batch, MB)를 적용하여 제조하였고, 표면저항과 인장특성에 대한 MB의 영향을 고찰하였다. 탄소필러로 카본블랙(CB), 탄소나노튜브(CNT), 그래핀나노플레이트(GNP)가 사용되었다. 나일론 6/탄소필러 복합체의 열적특성을 differential scanning calorimetry(DSC)를 이용하여 측정하였으며 결정화온도에서는 큰 폭의 증가를 나타내었으나 용융온도는 큰 변화를 보이지 않았다. X-ray diffraction(XRD)에 의한 결정구조 분석결과 나일론 6/탄소필러 복합체의 경우 a형 결정구조가 지배적임을 보여주었다. MB가 적용된 나일론 6/탄소필러 복합체의 지수법칙 계수(n)와 위상각이 감소하였고, 이는 MB가 적용될 때 탄소필러 분산성이 개선되는 간접적인 증거로 설명할 수 있다.
