STUDIES OF THE INFLUENCE ON THE HEAT-CONDUCTING PROPERTIES OF NANOCOMPOSITES OF THE TEMPERATURE REGIME OF THEIR PREPARATION

The results of experimental studies of the dependence of the heat conductivity of nanocomposites based on polypropylene filled with carbon nanotubes on the level of overheating of the polymer melt relative to its melting temperature are presented. It was found that with an increase in this level, the value of the heat conductivity coefficient of composites increases. It is shown that when a certain overheating is reached, its further growth does not provide an increase in the heat conductivity of nanocomposites. On the basis of the obtained regularity, the value of the rational level of overheating was determined.
