热处理对MEH-PPV薄膜微力学行为的影响
Effect of heat treatment temperature on micro mechanical behavior of MEH-PPV thin film
摘要
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 governed mainly by the topological entanglement, rather than the cohesive entanglement.关键词
