摘　　要：将聚乙烯(PE)和氧化铝(AO)熔融共混制得综合性能更好的PE/AO复合材料。通过对其进行流变分析、热力学性能分析、力学性能分析、导热性能分析和断面微观结构分析,探究AO质量分数对复合材料结构及性能的影响。结果表明,随着AO质量分数的增加,复合材料逐步转为脆性材料,其弹性模量、屈服强度、导热系数、储能模量同步增加;当AO质量分数为10%时,复合材料的断裂强度为18.2 MPa,综合性能最好。Polyethylene(PE)and aluminium oxide(AO)are fused to prepare PE/AO composites with better comprehensive properties.The effect of AO mass fraction on the structure and properties of the composites is investigated by rheological analysis,thermodynamic analysis,mechanical analysis,thermal conductivity analysis and section microstructure analysis.The results show that the elastic modulus,yield strength,thermal conductivity and energy storage modulus of the composite gradually become brittle with the increase of AO mass fraction.When the AO mass fraction is 10%,the fracture strength of the composite is 18.2 MPa,and the comprehensive performance is the best.
