초록

본 연구에서는 전기방사법(electrospinning method)을 이용하여 다중벽 탄소나노튜브(multi-walled carbon nanotubes, MWCNTs)가 첨가된 polyacrylonitrile (PAN)과 poly (methyl methacrylate) (PMMA) 고분자 복합 나노섬유를 합성하였다. 합성 과정에서 고분자 물질의 농도와 인가전압의 변화가 나노섬유의 합성에 미치는 영향을 조사하여 최적화된 고분자 나노섬유 합성 조건을 확립하였다. 또한, MWCNTs의 첨가량의 변화에 따른 복합 나노섬유의 구조적 특징을 주사전자현미경(scanning electron microscopy)과 투과전자현미경(transmission electron microscopy)을 통해 분석하였으며, 기계적 강도를 조사하였다. 5 wt%의 MWCNTs가 첨가된 경우, 인장강도(tensile strength)와 영률(Young's modulus)이 PAN 복합 나노섬유는 500%, 27% 향상되었으며, PMMA 복합 나노섬유는 250%, 1,017% 향상된 것을 확인할 수 있었다.

Multi-walled carbon nanotubes (MWCNTs) incorporated polyacrylonitrile (PAN) and poly (methyl methacrylate) (PMMA) nanofibers were synthesized using electronspinning method. Effects of polymer concentration and applied voltage on the synthesis of PAN and PMMA nanofibers were systematically investigated. The structural characterization of PAN/MWCNTs and PMMA/MWCNTs composited nanofibers synthesized as a function of the MWCNTs concentration was performed by scanning electron microscopy and transmission electron microscopy. 5 wt% MWCNTs incorporated PAN and PMMA electrospun nanofiber exhibit best strength and stiffness.
