Manufacturing and Characterization of Nano-composites with Chemically Functionalized Multiwalled Carbon Nanotubes

기능화된 다중벽 탄소나노튜브 복합재료의 제조 및 물성 평가에 대한 연구

Chemically modified multiwalled carbon nanotubes with acids were incorporated into a epoxy matrix by in situ polymerization process, to improve the transfer of mechanical load through chemical bonds, which were demonstrated by infrared spectroscopy. And the mechanical properties of epoxy/carbon nanotube composites were measured to investigate the role of carbon nanotubes. The epoxy/carbon nanotube composites shows higher tensile strength and wear resistance than existing epoxy, with 1 or 2 wt. % addition of functionalized carbon nanotubes. The tensile strength with 7 wt. % carbon nanotibes is increased by a 28% and the wear resistance in exceptionally increased by an outstanding 100 times.
