How it works: Many triboelectric series have been established but, although there is some agreement amongst them, most of these series are very dissimilar, even when the same materials are used. However, the ability of a material for gaining/losing electron and thus the severity of the effect depends on materials polarity. rubber, Copper brushes used in It usually lists materials in order of decreasing tendency to charge positively (lose electrons), and increasing tendency to charge negatively (gain electrons). Charge is transferred through the transfer of electrons, the direction of the transfer depending on the specific materials involved. Items in the Triboelectric series are used for generating static electricity. This list of materials is known as the triboelectric series. The following Triboelectric Series shows which materials will work the best to create static electricity when rubbed together. Resources for ffor series Time Traveler! Piezoelectric crystals, ceramics and polymers have useful applications in many industries. Digital Electronics will charge the glass with positive charges.
