摘　　要：可延展的电子产品在可穿戴电子、柔性显示和医疗等等产品中有很大的应用潜力。文章中模拟界面的微观性质,对PDMS/铜纳米颗粒复合物的特性进行计算,探讨其与模拟温度之间的关系。模拟结果表明,PDMS/铜纳米颗粒复合物为各向同性的无定形结构,铜纳米颗粒与PDMS基体之间通过较强的范德华作用力结合在一起,铜纳米颗粒表面多个原子层呈现无定形态。揭示了界面区域随颗粒数目和温度的变化规律。加入铜纳米颗粒形成复合物可以得到不同于PDMS的力学新特性。Stretchable electronics have great potential in the application of wearable electronics, flexible displays and healthcare and so on. Simulate the microscopic properties of interface. PDMS/copper-nanoparticle composites are implemented to investigate their relationships between the simulation temperature. The results demonstrate that the PDMS/copper-nanoparticle composites are isotropic amorphous structure, in which the copper nanoparticles combine with PDMS matrix due to van der Waals effect and multi-layers of atoms on nanoparticle surface change into amorphous configurations. New nanocomposites with Cu nanoparticle filler, indicating the remarkably different mechanical properties of
