초록

본 연구에서는 탄소나노튜브, 니켈 및 산화아연의 항균특성 활용을 목적으로 새로운 항균 나노 복합 재료를 개발하였다. 니켈 코팅된 탄소나노튜브의 제조 및 그들의 동시발생 집중 및 비활성 세균에 대한 항균소재의 잠재적 응용성을 평가하였다. 제조된 니켈 도금 탄소나노튜브의 형상 및 니켈 도금은 전계 방출 주사전자현미경(FE-SEM) 및 X선 에너지 분산 분광기(EDS)를 사용하여 분석하였다. 나노복합소재의 항균 특성을 확인할 수 있는 타깃 세균은 황색포도상구균과 대장균으로 지정하였다. 니켈 도금된 탄소나노튜브와 산 처리된 탄소나노튜브로 각각 강화된 나노복합소재의 황색포도상구균 및 대장균에 대한 항균특성을 비교하였을 때, 니켈 도금된 탄소나노튜브/산화아연으로 강화된 나노복합소재의 항균 특성이 더 우수한 결과를 보이는 것을 확인할 수 있었다. 이러한 결과에 따라서, 탄소나노튜브 표면에 도금된 니켈이 복합소재 내에서 세균의 살균 작용에 중요한 역할을 하는 것으로 판단할 수 있다. 또한, 첨가된 산화아연은 나노복합소재의 항균특성 향상을 목적으로 제안되었다.

This study was conducted to develop novel antimicrobial nano-composites, with the aim of fully utilizing antimicrobial properties of multi-walled carbon nanotubes (MWCNTs), nickel (Ni) and zinc oxide (ZnO). Ni coated-MWCNTs (Ni-CNT) were prepared and evaluated for their potential application as an antimicrobial material for inactivating bacteria. Field emission scanning electron microscopy (FE-SEM), and X-ray energy dispersive spectroscopy (EDS) were used to characterize the Ni coating and morphology of Ni-CNT. Staphylococcus aureus (S. aureus) and Escherichia coil (E. coil) were employed as the target bacterium on antimicrobial activities. Comparing with the nitric acid treated MWCNTs and Ni-CNT which have been previously reported to possess antimicrobial activity towards S. aureus and E. coil, Ni-CNT/ZnO exhibited a stronger antimicrobial ability. The nickel coating was confirmed to play an important role in the bactericidal action of Ni-CNTs/ZnO composites. Also, the addition of ZnO to the developed nanocomposite is suggested to improve the antimicrobial property.
