Validity of Several Thermal Conductivity Models in Metal Oxide Nanoparticles Filled Polycarbonate

Article Preview

Abstract:

The thermal conductivity (TC) of compression moulded polycarbonate (PC) and PC filled with 2.5-5% iron oxide (α-Fe2O3), cupric oxide (CuO) or magnesium oxide (MgO) nanoparticles, prepared by extrusion, was studied using a thermal conductivity analyser (TCA). The effect of type and content of nanoparticles on the thermal conductivity was investigated. The experimental TC values of the PC nanocomposites showed an increase with an increase in the level of nanoparticles concentration. The TC improvement in PC/CuO nanocomposite was greater than that of other nanocomposites. Several models were used for prediction of the TC in the nanocomposites. In all nanocomposites the TC values correlated well with the values predicted by the Ce Wen Nan model up to 5wt%.
