Thermal conductivity of highly filled polymer nanocomposites
Source abstract
Abstract
A model is developed for the effective thermal conductivity of composites with polymer matrices reinforced with randomly distributed micro- and nano-particles. The model takes into account formation of infinite conducting paths and finite aggregates of particles on the one hand, and thermal barriers at the interfaces between the matrix and filler, on the other. Material parameters are determined by matching observations on a number of composites with ceramic and carbon fillers. The intensity of thermal barriers is evaluated by means of the Kapitza radius. Comparison of experimental data with results of simulation demonstrate that this parameter is determined by filler only, and it is weakly affected by the matrix material.
