HDPE经过γ射线辐照后,其分子链上引入了羰基等含氧极性基团,极性提高.通过在HDPE/氧化铝(Al2O3)体系中加入辐照HDPE以及协同增容剂(Synergist),体系的界面相互作用增强,力学性能明显提高.由于Al2O3具有优良的导热性能,因此,HDPE/Al2O3的热导率明显提高.研究结果表明,与HDPE相比,V(HDPE)/V(γ-HDPE)/V(2% Synergist处理Al2O3 )=56/14/30体系的拉伸强度从26.3 MPa提高到32.4 MPa,冲击强度从23.2 kJ/m2提高到35.9 kJ/m2;此时,体系的导热系数由0.46 W/(m·K)增加到1.14 W/(m·K).
