Performance enhancement of epoxy/carbon nanocomposites via amine-functionalization of carbon nanofillers |
| 초록 |
The best performance of an epoxy/carbon nanocomposite with carbon nanofiller would be resulted from the homogeneous dispersion of the nanofiller and strong interfacial bonding between the epoxy matrix and the nanofiller. The purpose of this study is to examine the influence of introducing amine groups on the surfaces of carbon nanofillers (carbon nanofibers(CNFs) and multi-wall carbon nanotubes(MWNTs)). An amine functionalization of the carbon nanofillers was carried out via treating pristine them with 4-aminobenzoic acid in polyphosphoric acid. FT-IR spectroscopy, XPS, TGA and FE-SEM were used to confirm the functionalization. Epoxy nanocomposites comprising the pristine or functionalized carbon nanofillers were prepared and their curing behavior and thermo-physical properties were compared to each other. Fracture surfaces of the nanocomposites were investigated by FE-SEM. The functionalized MWNTs induced strong interfacial bonding than the functionalized CNFs and resulted in a considerable performance improvement of the nanocomposite. |
