Metal materials are poor in chemical corrosion resistance and insulation performance, inorganic materials have higher processing costs, and carbon materials have poor mechanical properties. 
The increase of the overall thermoelastic coefficient of the thermal conductive filler and the polymer matrix will lead to the increase of the thermal conductivity of the composite, and the thermal conductivity of the composite generally will not change dramatically, but will only gradually increase. 2 Factors Affecting Thermal Conductivity 2.1 Type and Amount of Filler There are three types of thermal conductive fillers: metal fillers, inorganic fillers and carbon-based fillers.
This is because the filler with larger particle size will have more space in the matrix with the increase of filling amount, affecting heat transfer.
The maximum in-plane thermal conductivity of the composite paper is 21.7 W/(m·K), and it has excellent mechanical and insulation properties. 2.3.2 Surface treatment There is a great difference between the surface tension of the thermal conductive filler and the matrix, and it is easy to form segregation.

Series of experiments were executed to measure the effect of the type and the concentration of the applied waste materials on the thermal conductivity and mechanical properties of the final brick product.
Our measurements indicate that the seed-shell additive had affected the insulating properties the most (up to 37% less thermal conductivity).
The mechanical tests also show the same decrease of the measured properties as a function of concentration of the added organic waste materials.
The similarity of the change in properties is caused in all cases by the pore structure as it determines all these properties.
From the point of view of the mechanical properties the most applicable additive is the saw dust.
