Development of polymer nanocomposites with enhanced thermal conductivity

Thermal conductivity is an important property of the material, especially in certain industrial products. Polymer materials usually have very low thermal conductivity, which determines them in some applications. Namely, heat wastage during the operation of electrical equipment is crucial for extending their lifespan, especially for polymer insulation materials that are prone to thermal aging. In the scope of the KK.01.2.1.02 project, Končar GIM and the Faculty of Chemical Engineering and Technology are developing an improved insulation system. It is based on impregnation resin with enhanced thermal conductivity achieved by the incorporation of oxide nanoparticles. The effect of nanofiller particle size and concentration on the thermal conductivity of cured nanocomposite resin was measured with the transient hot bridge method. The thermal conductivity increased up to 11% with 5 wt% of nanofiller. Further, the thermal stability of resin nanocomposites showed a minor increase as was determined by thermo- gravimetric analysis (TGA). In addition, the curing process effectiveness was evaluated by differential scanning calorimetry (DSC).
