Contact Electrification and Adhesion Between Dissimilar Materials
Science, 1992Simultaneous measurements of surface force and surface charge demonstrate strong attraction due to the spontaneous transfer of electrical charge from one smooth insulator (mica) to another (silica) as a result of simple, nonsliding contact in dry nitrogen.

Thermionic return currents in contact electrification
Journal of Applied Physics, 1977It is demonstrated that the contact electrification process is generally a nonequilibrium phenomenon. The electrochemical potential is considered for the case of ion transfer between insulators. It is shown that the thermionic return currents are significantly dependent on the physical separation and the dielectric constants of the materials.

Contact electrification of alkali halides
Journal of Electrostatics, 1993Abstract A recently cleaned metal transfers strong positive charge to the surface of an alkali halide crystal. But a metal which has made several (3–30) previous contacts to the alkali halide transfers a much smaller and usually negative charge.

Contact electrification of corona-treated polyethylenes
Journal of Electrostatics, 1981Abstract The influence of the corona treatment dose on the contact electrification characteristics of unfilled low density (LDPE) and TiO 2 -filled medium density (MDPE) polyethylene films was determined by measuring the surface charge after contact with a biased gold counterelectrode.

Contact electrification of solid particles
Proceedings of the Physical Society, 1941Solid particles carry with them electrostatic charges from contact with the storage vessel. The sign of the charge acquired in the air of the laboratory was determined for metal particles which were poured either from a silica bowl or from a glass beaker, and for particles of insulators and semiconductors which parted contact with containers of silica,

Surface Contamination and Contact Electrification
1987When two materials are touched together and then separated, we find, in general, that charge has transferred between them. This phenomenon is known as contact electrification or contact charging. It is most apparent when one or both of the contacting materials is an insulator, because of the ability of an insulator to retain charge. Contact charging is
