Abstract: By using Differential Scanning Caborimetry (DSC), Thermogravimetric (TG) thermal analysis ect, we determined thermal physical properties, such as the heat conduction performance, specific heat capacity, heat stability and ect, of different metal oxide/Nylon posites. The results show that after added ZnO,CuO,Fe3O4 in PA1010 matrix, the thermal conductivity posites linear increases with the increasing of the quality score of metal oxide. The thermal conductivity posites is related closely to the species of the thermal conductivity filler,CuO>Fe3O4>ZnO. When using ZnO as thermal conductive filler and the particle diameter ranges 35 to 40 μm, heat conduction performance of the posites is the best, The thermal conductivity of ZnO/posites linear increases with the temperature increasing. The heat capacity of Nylon 1010 and all kinds of metal oxide/Nylon 1010 increases gradually with the temperature rising. In the same temperature, heat capacity of the posites reduces gradually with the content of metal oxide increasing. The glass transition temperature of Nylon 1010 is about 47℃ or so. Adding metal oxide improves the thermal stability posites and the size of the thermal stability of the different kinds of metal oxide/nylon posites is as follows: CuO>Fe3O4>ZnO.
