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。
Extensive electronic products have great potential in products such as wearable electronics, flexible displays and medical applications. In this paper, the microscopic nature of the simulated interface is used to calculate the properties of the PDMS / copper nanoparticle composites and the relationship between them and the simulated temperature. The simulation results show that the PDMS / copper nanoparticle composites are isotropic amorphous structure, copper nanoparticles and PDMS matrix by strong van der Waals force together, multiple atomic layers on the surface of copper nanoparticles appear amorphous form. The variation of interface area with particle number and temperature was revealed. Addition of copper nanoparticles to form a composite can yield new mechanical properties different from PDMS.
