聚合物支撑的金属薄膜作为柔性、大面积电子器件的互连材料，在拉伸时会发生断裂，而断裂应变强烈地依赖于薄膜/基板的界面性质。采用有限元方法和粘聚区模型(CZM)模拟了金属膜和膜/基界面的微观结构，研究了界面性质对金属膜延展性的影响。系统地研究了基片厚度、基片材料的杨氏模数、膜/基片界面刚度、强度和界面断裂能等系统参数对聚合物支撑金属薄膜延展性的影响。结果表明，聚合物支撑金属薄膜的延展性随界面强度的增加而增加，但增加的趋势明显受界面刚度的影响。
Polymer-supported metal films as interconnects for flexible, large area electronics may rupture when they are stretched, and the rupture strain is strongly dependent upon the film/substrate interfacial properties. This paper investigates the influence of interfacial properties on the ductility of polymer-supported metal films by modeling the microstructure of the metal film as well as the film/substrate interface using the method of finite elements and the cohesive zone model (CZM). The influence of various system parameters including substrate thickness, Young’s modulus of substrate material, film/substrate interfacial stiffness, strength and interfacial fracture energy on the ductility of polymer-supported metal films is systematically studied. Obtained results demonstrate that the ductility of polymer-supported metal films increases as the interfacial strength increases, but the increasing trend is affected distinctly by the interfacial stiffness.
