A long debate on the charge identity and the associated mechanisms occurring in contact‐electrification (CE) (or triboelectrification) has persisted for many decades, while a conclusive model has not yet been reached for explaining this phenomenon known for more than 2600 years! Here, 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… 

Electron Transfer in Nanoscale Contact Electrification: Effect of Temperature in the Metal–Dielectric Case

TLDR
A thermionic-emission band-structure model is proposed to describe the electron transfer between two solids at different temperatures and suggests that CE can occur between two identical materials owing to the existence of a local temperature difference arising from the nanoscale rubbing of surfaces with different curvatures/roughness.

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

Probing Contact‐Electrification‐Induced Electron and Ion Transfers at a Liquid–Solid Interface

TLDR
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.

Electron Transfer in Nanoscale Contact Electrification: Photon Excitation Effect

TLDR
The results suggest that there exists a threshold photon energy for releasing the triboelectric charges from the surface, which is 4.1 eV, and a photoelectron emission model is proposed to describe light-induced charge decay on a dielectric surface.

TLDR
Electrostatic charges on Teflon produced by rubbing with Lucite were directly identified as electrons rather than ions by electrochemical (redox) experiments with charged Tflon used as a single electrode in solution causing various chemical reactions.

Contact electrification of insulating materials

Manipulating nanoscale contact electrification by an applied electric field.

TLDR
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.

TLDR
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.

An experimental investigation of the static electrification of metal/metal surfaces shows that the erratic results normally obtained are owing to there being more than one cause, and that the

The absence of redox reactions for palladium(II) and copper(II) on electrostatically charged Teflon: relevance to the concept of "cryptoelectrons".

TLDR
Direct evidence is provided, based on X-ray photoelectron spectroscopy (XPS), that the surface charge created on these surfaces does not reduce copper and palladium ions, and instead, rubbing Teflon with PMMA causes material exchange and promotes adsorption of copper ions from aqueous solutions onto the rubbed Tflon; this process can be misinterpreted as an electrochemical reduction.
