Establishing the influence of the type of micro- and nanofillers on the thermophysical properties of highly heat conductive polymer composites based on polyamide 6

The object of this study is the thermophysical properties polymer micro- and nanocomposites, as well dependence their heat conductivity with structural characteristics when using different types fillers. A set experimental studies specific capacity nanocomposite materials for polyamide 6 carbon nanotubes, copper aluminum matrix fillers was carried out. When obtaining composites, a method used that based on mixing components in melt. content varied from 0.3 to 10 %, temperature composite – 305 500 K. Experimental dependences coefficients studied composites filler were derived. It established according value these order reduction, are ranked follows: copper, aluminum. found only one percolation threshold observed, matrix. regularities changes under consideration varying within above limits investigated. analysis influence degree crystallinity investigated shown an increase fillers, decreases. relationship between thermally conductive specified has been established. Higher values correspond lower crystallinity. reported results can be widely development highly various engineering applications.
