The outcome of this short review helps identify the important keys that influence the conductive polymer composites as functional materials.
Thermal conductivity is the degree of heat transfer to conduct heat in between a material.
Polymers One of the fundamental materials of a conductive polymer composites are the polymer matrix.
For the case of composite materials, more interfaces present between the polymer matrix and the fillers which leads to more scattering.
