Bending of few-layer graphene leads to interlayer slip, and slipping lowers the bending stiffness. Beyond a critical bending angle, the graphene layers bend like a stack of paper, with a state of superlubricity for interlayer slip.

滑倒弯曲。

几层石墨烯的弯曲会导致层间打滑，打滑会降低弯曲刚度。超过临界弯曲角时，石墨烯层像一叠纸一样弯曲，并具有超润滑状态以实现层间打滑。
