摘要
石墨烯作为一种新型碳纳米材料,因其优异的力学、电学和热学性能,在柔性电子器件领域具有巨大的应用潜力。在柔性器件中,石墨烯/柔性基底的界面力学性能决定了器件性能的可靠性。基于此,从实验测试技术(Raman光谱、原子力探针技术和鼓泡实验)和理论计算模型(一维线性模型、一维非线性模型、双线性内聚力模型及二维非线性模型) 2个方面综述了石墨烯/柔性基底的界面力学性能最新研究进展,并介绍了基于界面力学研究的石墨烯柔性器件相关应用及难点,最后展望了后期研究与应用方向。
As a carbon nanomaterial, graphene exhibits the superior mechanical, electrical and thermal properties, indicating an enormous application potential in the field of flexible electronic devices. In flexible devices, interfacial mechanical performance between graphene and flexible substrate can determine the reliability of devices performance. This review represented recent development on the interfacial mechanical performance of graphene/flexible substrate, i.e., experimental technology(by Raman spectroscopy, atomic force microscopy and pressurized blister test) and theoretical calculation model(shear-lag theory, nonlinear shear-lag analysis, bilinear cohesive law and two-dimensional nonlinear shear-lag mode). In addition, the relevant applications and difficulties of flexible graphene devices based on its interfacial mechanical research were also introduced. Finally, the future research and application were prospected.
