An epoxy-nanocomposite material was developed through the use of functionalized Multi-wall Carbon Nanotubes (F-MWCNTs) by dissolving 1wt% loading of F-MWCNTs into an organic solvent using sonication and then incorporating it into the polymer matrix (Epon 862) and curing agent (Epicure W) by utilizing in-situ polymerization process. The surface chemical reaction of the F-MWCNTs was characterized using Fourier Transform Infra-red (FTIR), Raman Spectroscopy, and Thermoagravrimetric Analysis (TGA). Raman Spectroscopy and FTIR were used to identify the functional groups and other organic materials on the surface or side walls of the MWCNTs. Raman Spectroscopy determined their structural properties. TGA was used to determine the decomposition behavior of the organic materials on the F-MWCNTs. The flexural and thermal properties of the epoxy nanocomposites were tested using Zwick (Roell 2.5) and Dynamic Mechanical Analysis (DMA) setups respectively. The morphology, dispersion of MWCNTs, and fracture characterization of the epoxy nanocomposites were determined using a Scanning Electron Microscopy (SEM). Functionalization not only improved the dispersion of MWCNTs in the polymer matrix, it also enhanced the mechanical properties of the three nanocomposite systems. | | ISBN: | 1-4200-6182-8 |
