This Review discusses ionic electrets: their preparation, their mechanisms of formation, tools for their characterization, and their applications. An electret is a material that has a permanent, macroscopic electric field at its surface; this field can arise from a net orientation of polar groups in the material, or from a net, macroscopic electrostatic charge on the material. An ionic electret is a material that has a net electrostatic charge due to a difference in the number of cationic and… 

Electrostatic Charging Due to Separation of Ions at Interfaces: Contact Electrification of Ionic Electrets

This Review discusses ionic electrets: their preparation, their mechanisms of formation, tools for their characterization, and their applications. An electret is a material that has a permanent,

Effect of Surface Pre-Charging and Electric Field on the Contact Electrification between Liquid and Solid

: Contact electri fi cation at the solid − liquid interface is a ubiquitous phenomenon. In spite of the extensive studies about its origin, it remains di ffi cult to reveal the mechanism of charge

Patterns of electrostatic charge and discharge in contact electrification.

TLDR
It is concluded that the transfer of ions between the contacting surfaces is the most common mechanism for charge separation when organic materials are involved, and this study demonstrates the wealth of quantitative information it can provide as a tool for studying the atomic/molecular mechanisms of contact electrification.

Contact de-electrification of electrostatically charged polymers.

TLDR
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.

Selective discharge of electrostatic charges on electrets using a patterned hydrogel stamp.

TLDR
A topographically patterned hydrogel stamp is used to expose electrets purposely and selectively to water for discharging, hence leaving the electrostatic charges in the noncontacted area to achieve high-resolution charge patterns; by applying “single electrode” electrochemical reductions in the charged area, the authors can also obtain a variety of metallic microor nanostructures on electrets.

The Charging Events in Contact-Separation Electrification

TLDR
The mechanism of CE is refined, providing information for rethinking the conventional ranking of materials’ charging abilities, charge harvesting, and charge prevention, and a large contribution to tribocharge harvesting comes, in fact, from the electrostatic induction resulting from the generated CE charges.

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
The fabrication and characterization of ionic electrets-materials that bear a long-lived electrostatic charge because of an imbalance between the number of cationic and anionic charges are described.

Direct observation of ion transfer in contact charging between a metal and a polymer

Triboelectric charging between metals and insulators is usually thought to involve electron transfer. Doping some polymers with a small amount of salt can significantly change their charging

A tool for studying contact electrification in systems comprising metals and insulating polymers.

TLDR
An analytical system for in situ measurement of the charge that develops by contact electrification when a ferromagnetic sphere rolls on the surface of a polymer, which generates an internally consistent set of data that include the polarity and magnitude of charging for a homologous series of polymers that differ chemically in the pendant group on a polyethylene backbone.
