materials does not change and remains invariant when the dispersion, specific surface area of the particles and this surface
places of the components change, i.e. state.

hence its properties, including thermal conductivity [1; 2].

If the PCM has a filler content of 0,5 < < 1by volume, Kiev: Technique, 1985. - 152 p.
then the polymer is the binder. That is, in such a material,
the volume bulk is occupied by filler, which particles are [2] Godovskiy Yu. K. Thermal physics of polymers, -M.:
