Abstract:
Thermophysical properties of graphite plastics based on aromatic polyamide phenylone are studied in the article. It is shown that the introduction of graphite leads to a decrease in the mobility of the structural elements of the macromolecular chains of the polymer matrix due to the intermolecular interaction at the polymer-filler interface. It was found that with increasing graphite content the degree of orientation of the amorphous phase increases during crystallization and a conformational set of structural units occurs. It was found that the selected filler promotes an increase in thermal conductivity and thermal diffusivity of 5,5 and 3,2 – 5,0 times depending on temperature.
Keywords: graphite plastics, aromatic polyamide, specific heat, thermal conductivity, thermal diffusivity, thermal capacity jump.
