초록

본 연구는 표면처리에 따른 탄소나노튜브의 표면특성변화가 탄소섬유 강화 복합재료의 기계적 물성에 미치는 영향에 대하여 살펴보았다. 표면처리된 탄소나노튜브의 표면특성은 산-염기도 측정, FTIR, 그리고 XPS를 통하여 알아보았다. 복합재료의 기계적 계면특성은 층간전단강도(interlaminar shear strength; ILSS)와 임계응력세기인자(critical stress intensity factor; $K_{IC}$)를 통하여 고찰하였다. 실험결과 산-염기 상호반응에 의한 각각의 표면처리된 탄소나노튜브의 표면특성의 변화를 가져오며, 산처리한 MWNTs/탄소섬유/에폭시 복합재료의 경우 미처리 MWNTs, 염기 처리 MWNTs와 비교하여 우수한 기계적 물성을 보였다. 이는 산성을 가지는 MWNTs와 염기성의 에폭시 수지가 산-염기 및 수소결합에 의한 계면 결합력의 향상 때문이라 판단된다.

In this work, the effect of chemical treatments of multi-walled carbon nanotubes (MWNTs) on the mechanical interfacial properties of carbon fiber fabric-reinforced composites was investigated. The surface properties of the MWNTs were determined by acid and base values, Fourier transform infrared spectroscopy (FTIR), and X-ray photoelectron spectroscopy (XPS) analyses. The mechanical interfacial properties of the composites were assessed by interlaminar shear stress (ILSS) and critical stress intensity factor ($K_{IC}$). The chemical treatments based on acid and base reactions led to a significant change of surface characteristics of the MWNTs, especially A-MWNTs/carbon fibers/epoxy composites had higher mechanical properties than those of B-MWNTs and non-treated MWNTs/carbon fibers/epoxy composites. These results were probably due to the improvement of interfacial bonding strength, resulting from the acid-base interaction and hydrogen bonding between the epoxy resins and the MWNT fillers.
