Thermal degradation of epoxy composites based on thermally expanded graphite and multiwalled carbon nanotubes

Thermal degradation of epoxy composites filled with various carbon materials (thermally expanded graphite, multiwalled carbon nanotubes) was studied. The dynamics of the thermal degradation of epoxy composites was evaluated by thermogravimetric analysis in the temperature range of 55–700°С (heating rate 10 deg min–1) in an oxidizing medium. Carbon fillers were studied by scanning electron microscopy, transmission electron microscopy, and low-temperature nitrogen adsorption. The influence of the composite preparation procedure on its thermal stability was determined. The type of filler significantly influences the thermal oxidative degradation of the composites.
