Abstract By using Differential Scanning Caborimetry (DSC), Thermogravimetric (TG) thermal
analysis etc, we determined thermal physical properties, such as the heat conduction performance,
specific heat capacity, heat stability and etc, of different metal oxide/Nylon posites. The
results show that after added ZnO, CuO, Fe3O4 in PA1010 matrix, the thermal conductivity of
composites linear increases with the increasing of the quality score of metal oxide. 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◦C or so, and adding metal oxide can improve
the therm
