Electrically insulating objects gain a net electrical charge when brought in and out of contact. This phenomenon—triboelectricity—involves the flow of charged species, but conclusively establishing their nature has proven extremely difficult. Here, we demonstrate an almost linear relationship between a plastic sample’s net negative charge and the amount of solution metal ions discharged to metallic particles with a coefficient of proportionality linked to its electron affinity (stability of...[Show more]
