Abstract

An enduring question in science has been why sliding plays a major role in the triboelectric generation of static electricity–the “tribo” in triboelectricity. We provide here a general explanation which is rooted in established science. When sliding is taking place, there is symmetry breaking due to elastic shear, so the front of the sliding body experiences different elastic strains from the back. Consequently the polarization and associated charges at the front and back are not the same, and the difference between the two leads to current flow similar to the difference in air pressure above and below a plane’s wing leading to lift. Specific calculations are provided which show good agreement with prior experimental measurements of size and shape dependencies, and reasonable quantitative agreement with experimental current measurements.

是什么让 "Tribo "成为 "Triboelectricity"？

科学界一个永恒的问题是，为什么滑动在静电的三电产生中起着重要作用？我们在此提供一个植根于成熟科学的一般性解释。当滑动发生时，由于弹性剪切力的作用，对称性会被打破，因此滑动体的前部与后部会经历不同的弹性应变。因此，前后的极化和相关电荷不一样，两者之间的差异导致电流流动，类似于飞机机翼上下的气压差异导致升力。具体计算结果与之前的尺寸和形状依赖性实验测量结果非常吻合，与实验电流测量结果在数量上也非常吻合。
