Carbon nanotubes(CNTs) have been attracting more attention worldwide because of their superior thermal and electrical properties. Epoxy resins are well established as thermosetting matrice of advanced composites, displaying a series of promising characteristics for a wide range of application. The incorporation of CNTs into epoxy resin bulk materials will surely enhance the thermal and electrical properties of epoxy resins. In this work, the thermal and electrical properties of chemically treated multiwalled carbon nanotubes(MWNTs)-dispersed difunctional epoxy composites were investigated. The composites containing 0, 0.5, 1.0, 1.5 and 2.0 wt% MWNTs have been studied by differencial scanning calorymeter(DSC), thermogravimetric analysis(TGA), and specific resistance measurements. The MWNTs-dispersed epoxy nanocomposites were discussed in surface characteristics by measuring pH, acid values, and Fourier transform-infrared(FT-IR) spectroscopy. |
