The thermal conductivity of the thermally conductive polymer material is determined by the polymer matrix, the thermally conductive filler and their mutual impregnation. There is no uniform and dense ordered crystal structure or charge carriers required for thermal communication in the polymer matrix, and the thermal conductivity is relatively poor.

As a thermally conductive filler, whether it is in the form of particles, flakes, or fibers, its thermal conductivity is higher than that of the polymer matrix itself. When the addition amount of the thermally conductive filler is very small, the interfering and mutual infiltration cannot be formed between the thermally conductive fillers, which is almost meaningless to the advancement of the thermal conductivity of the polymer material; only when the added amount of the thermally conductive filler reaches a certain amount in the polymer matrix At a critical value, the thermally conductive fillers can be meaningfully impregnated with each other, and the system can form a network-like or chain-like form, that is, the thermally conductive network chain.

When the orientation of the thermal network chain is the same as that of the heat flow target, the heat conduction function advances quickly; when the heat flow target is not formed in the system, the thermal resistance of the heat flow target will be large, and the heat conduction performance will be poor.

Therefore, how to form a heat-conducting network chain on a large level in the system for the purpose of heat flow has become the key address for the advancement of the heat-conducting function of heat-conducting polymer materials.
