摘要

我们通过实验证明，石墨烯和氟化石墨烯在边缘表现出不同的滑动摩擦系数(氟化石墨烯从5.8×10-3到4.9×10-1;薄片样品的石墨烯从8.2×10-3到3.3×10-1)与内部(氟化石墨烯从5.1×10-3到1.5×10-1;石墨烯从2.5×10-2到2.3×10-1)在环境湿度条件下(~ 40-60%)。原子力显微镜(AFM)证明了石墨烯和氟化石墨烯之间的摩擦系数具有明显的方向依赖性。

Why orthotropic friction is important on graphene and graphene fluoride thin films

We experimentally demonstrate that graphene and graphene fluoride manifest different coefficients of sliding friction at the edges (graphene fluoride from 5.8×10-3 to 4.9×10-1; graphene from 8.2×10-3 to 3.3×10-1) of a sheet sample versus the interior (graphene fluoride from 5.1×10-3 to 1.5×10-1; graphene from 2.5×10-2 to 2.3×10-1) under ambient humidity conditions (~ 40-60%). Atomic force microscopy (AFM) was used to prove the friction coefficients show distinct directional dependence between graphene and graphene fluoride.
