论文摘要
通过摩擦不同材料的电气化是一种众所周知的现象，其历史开始了公元前五个以上的历史。但是，简单的实验可能导致矛盾或不一致的结果，并且这种现象的历史受到非直觉结果的困扰。例如，可以通过摩擦相同材料来进行摩擦电荷。在这项工作中，我们希望强调摩擦电性的一些历史方面，这些方面可以丰富本科物理学课程中对静电的讨论。我们将重点关注应变对样本的摩擦电特性的影响，我们认为这是物理教师并不众所周知的。我们将证明，可以通过摩擦不同半径的相同橡胶气球来获得强大的极性，我们还将证明这种充电方法在入门物理课程中可能非常有用。
Electrification by rubbing different materials is a well known phenomenon with a history that begun more than five centuries BC. However, simple experiments can lead to contradictory or inconsistent results and the history of this phenomena is plagued with non-intuitive results. For example, triboelectric charging by rubbing identical materials is possible. In this work we want to highlight some historical aspects of triboelectricity that could enrich the discussion of electrostatics in an undergraduate physics course. We will focus on the effect of strain on the triboelectric properties of a sample, which we think is not well known to physics teachers. We will show that it is possible to obtain robust polarities by rubbing identical rubber balloons of different radii and we will also show that this charging method can be very useful in introductory physics courses.
