Contact electrification of semiconductors
British Journal of Applied Physics, 1960Recently published experimental findings on the electrification of rutile powder by sliding down a metal chute can be explained by an extension of the present author's theory of the separation electrification of metals. The mechanism of the electrification of insulators must, in most cases, be quite different.

Ice‐crystal contact electrification
Quarterly Journal of the Royal Meteorological Society, 1960AbstractAn experimental investigation of electrification accompanying the momentary single contact of vapourgrown ice crystals at the same or at different temperatures suggests than any such effect is much smaller than might be expected from Reynolds's report on charging observed with riming spheres and vapour‐grown ice crystals.

Contact electrification and surface composition
Journal of Physics D: Applied Physics, 1995We have studied the charge transfer to polypropylene films containing varying concentrations of amide (donor) and fluorine (acceptor) groups grafted onto the polymer backbone. Pure polypropylene charges very weakly but the addition of amide causes the charging to become strongly positive, and fluorine causes it to become strongly negative.

Ion transfer in contact electrification
SPIE Proceedings, 1990The contact charge on polymers is influenced by added organic salts, and the charge is higher when the additive is polymer-bound rather than molecular.'7 In our studies, the presence of an ionomer consisting of a polystyrene random copolymer with pendent N-methylpyridinium toluenesulfonate groups in the host resin produces a positive charge, and the ...

Unveiling Contact‐Electrification Effect on Interfacial Water Oscillation
Advances in MaterialsWater is crucial for various physicochemical processes at the liquid–solid interfaces. In particular, the interfacial water, mediating the electric field and solvation effect along with the solid, corporately determine the electrochemical properties ...

Chemistry
Contact electrification (CE) is an emerging strategy for controlling the performance of metal nanoparticle (NP) catalysts. The underlying physical principle of this control is the sensitivity of the Fermi level to metal-metal contacts.

Contact electrification of insulating materials
Journal of Physics D: Applied Physics, 2011The electrostatic charge that is generated when two materials are contacted or rubbed and then separated is a well-known physical process that has been studied for more than 2500 years. Contact electrification occurs in many contexts, both natural and technological.
