Contact electrification (CE) (or triboelectrification) is a well‐known phenomenon, and the identity of the charge carriers and their transfer mechanism have been discussed for decades. Recently, the species of transferred charges in the CE between a metal and a ceramic was revealed as electron transfer and its subsequent release is dominated by the thermionic emission process. Here, the release of CE‐induced electrostatic charges on a dielectric surface under photon excitation is studied by… 
Probing Contact‐Electrification‐Induced Electron and Ion Transfers at a Liquid–Solid Interface
It is demonstrated that electron transfer plays the dominant role during CE between liquids and solids, which directly impacts the traditional understanding of the formation of an electric double layer at a liquid-solid interface in physical chemistry.
Unraveling Temperature‐Dependent Contact Electrification between Sliding‐Mode Triboelectric Pairs
The underlying mechanism on contact electrification (CE) has remained a topic of debate over centuries, and it is argued to be due to electron transfer, ion transfer, and/or even material species
Quantifying electron-transfer in liquid-solid contact electrification and the formation of electric double-layer
The authors demonstrate that the electron transfer paly an important role in liquid-solid contact electrification and the formation mechanism of electric double-layer is proposed.
Effects of Surface Functional Groups on Electron Transfer at Liquid-Solid Interfacial Contact Electrification.
The discoveries in this work support the "two-step" model about the formation of an electric double-layer (Wang model), in which the electron transfer occurs first when the liquids contact the solids for the very first time.


On the Electron‐Transfer Mechanism in the Contact‐Electrification Effect
A new method is reported to quantitatively investigate real-time charge transfer in CE via triboelectric nanogenerator as a function of temperature, which reveals that electron transfer is the dominant process for CE between two inorganic solids.
Manipulating nanoscale contact electrification by an applied electric field.
The modulation effect of the electric field on contact electrification is enhanced for a thinner dielectric layer and can potentially be utilized to enhance the output performance of energy harvesting devices or nullify contact electric charge transfer in applications where this effect is undesirable.
Water-solid surface contact electrification and its use for harvesting liquid-wave energy.
It is demonstrated that the contact electrification between water and insulating polymer films can also be useful for TENG, which can derive a new application of TENG especially in liquid environments for sensing.
Raising the Working Temperature of a Triboelectric Nanogenerator by Quenching Down Electron Thermionic Emission in Contact‐Electrification
By designing and preparing a rotating free-standing mode Ti/SiO2 TENG, the relationship between CE and temperature is revealed and it is found that the dominant deterring factor of CE at high temperatures is the electron thermionic emission.
Electrostatic charging due to separation of ions at interfaces: contact electrification of ionic electrets.
This Review proposes--as a still-unproved hypothesis--that this ion-transfer mechanism may also explain the ubiquitous contact electrification ("static electricity") of materials, such as organic polymers, that do not explicitly have ions at their surface.
Tribo-electric charging of dielectric solids of identical composition
Despite its long history and importance in many areas of science and technology, there is no agreement on the mechanisms responsible for tribo-electric charging, including especially the
Bipolar charge transfer induced by water: experimental and first-principles studies.
It was determined through experimental and first-principles calculations that water can also reverse the polarity of transferred charges and cause a bipolar charge transfer.
Contact de-electrification of electrostatically charged polymers.
This study describes a mechanism previously unreported in the context of contact electrification, "contact de-electrification", a process in which polymers charged to the same polarity discharge on contact, which appears to be general.
