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 1010 composites.The results show that after added ZnO,CuO,Fe_3O_4 in PAlOlO 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 40μm,heat conduction performance of the modified composites is the best.The thermal conductivity of ZnO/PA1010 composites 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 modified composites reduces gradually with the content of metal oxide increasing.The glass transition temperature of Nylon 1010 is about 47℃or so,and adding metal oxide can improve the thermal stability of composites.
