| 摘 要： | 利用纳米压痕技术研究了热处理对聚(2-甲氧基-5-(2’-乙基己基氧)-1-4-苯撑乙烯)(MEH-PPV)薄膜力学性能的影响,结果表明:随着热处理温度的提高,最大压痕深度先减小后增加,弹性模量、硬度随着热处理温度的提高而降低;另外,MEH-PPV薄膜对负载率的敏感性随热处理温度的提高而降低;同时利用高斯网络模型分析了热处理对MEH-PPV薄膜力学性能影响的原因,拓扑缠结对MEH-PPV薄膜力学性能影响是主要的,而凝聚缠结对MEH-PPV薄膜力学性能影响是次要的。

| Abstract: | The effect of heat treatment temperature on the micro mechanical behaviors of MEH-PPV thin film is studied by nanoindentation test.The elastic modulus and indentation hardness decrease with increasing quenching temperature.The sensitivity of the MEH-PPV film micro mechanical behaviors on the load rate is depressed when the quenching temperature increases.The effect of quenching temperature on the micro mechanical behaviors is analyzed by using Gauss network model,indicating that the mechanical behaviors are... |
