Abstract

The paper presents investigations into thermophysical, rheological, and morphological properties of graphitized carbon nanotube/polyoxymethylene composites containing 30 wt.% graphite and 0.1 wt.% nanotubes. It is shown that thermal conductivity and thermal diffusivity of graphitized carbon nanotube/polyoxymethylene composites increase respectively by 8 and 11 times in comparison with the original polyoxymethylene. And their melt flow index reduces approximately by 3.5 times. In spite of the abrupt decrease in the melt flow index, graphitized carbon nanotube/polyoxymethylene composites can be used in extrusion, jet molding and three-dimensional printing.
