卷对卷（R2R）干式转移是用于制造大规模二维（2D）材料和印刷柔性电子器件的重要工艺。现有的研究已经证明了2D材料在具有机械剥离的卷对卷设置中的干转移的可行性。然而，这一过程提出了一个重大的挑战，系统控制由于缺乏了解的机械剥离行为和复杂的非线性系统动力学。在这项研究中，一个R2R剥离过程模型的开发，以了解剥离过程中的参数，包括粘附能，剥离力，角度和速度之间的动态相互作用。仿真和实验研究进行了验证模型。结果表明，动态系统模型可以捕捉瞬态行为的R2R机械剥离过程，并用于过程分析和控制设计。
Roll-to-roll (R2R) dry transfer is an important process for manufacturing of large-scale two-dimensional (2D) materials and printed flexible electronics. Existing research has demonstrated the feasibility of dry transfer of 2D materials in a roll-to-roll setting with mechanical peeling. However, the process presents a significant challenge to system control due to the lack of understanding of the mechanical peeling behavior and the complexity of the nonlinear system dynamics. In this study, an R2R peeling process model is developed to understand the dynamic interaction among the peeling process parameters, including adhesion energy, peeling force, angle, and speed. Both simulation and experimental studies are conducted to validate the model. It is shown that the dynamic system model can capture the transient behavior of the R2R mechanical peeling process and be used for the process analysis and control design.
