Influence of Carbon Nanoparticles on Thermogravimetric Properties of Epoxy Nanocomposites

Keywords: ,

In this work polymer nanocomposite systems based on epoxy resin (ER), reinforced with carbon black (CB) or amine-modified multi-walled carbon nanotubes (MWCNTs) were studied. Thermogravimetric/Differential Thermal Analysis (TGA/DTA) and Dynamic Mechanical Analysis (DMA) techniques were carried out. Filler content was systematically varied in a wide range (0-2 wt. %). Our interest was focussed on the effect of different filler particles on the thermomechanical properties, degradation behavior and thermal stability of the nanocomposites. The dispersion of nanoparticles and the interactions between them and the epoxy matrix seem to play an important role on the thermal properties and molecular dynamics mechanisms, especially for higher filler concentrations.
