The triboelectric series is an important list of materials, which is created according to the tendency of materials to lose or gain electrons. The activity of electron transfer as a product of two bodies forming mutual contact with one another and the splitting is known as triboelectric charging. In such a process, one of the two bodies will ...

1.2: Triboelectric Effect. In an introductory course, the basic phenomena of electrostatics are often demonstrated with "pith balls" and with a "gold-leaf electroscope". A pith ball used to be a small, light wad of pith extracted from the twig of an elder bush, suspended by a silk thread. Today, it is more likely to be either a ping ...

The TriboElectric Effect Series Bill W. Lee, David E. Orr. When two different materials are pressed or rubbed together, the surface of one material will generally steal some electrons from the surface of the other material.The material that steals electrons has the stronger affinity for negative charge of the two materials, and that surface will be negatively …

Acrylic (a.k.a. plexiglass) is even better than glass — stronger effect and more reliable. You can get negative charges by rubbing a cotton t-shirt on a PVC rod and positive charges by rubbing the same shirt on an acrylic rod. The charging of the Teflon and/or glass can be shown by (1) attracting light objects such as Styro puffs, 3 (2 ...
