A Review: Contact Electrification on Special Interfaces

Frontiers in Materials, 2022
The contact electrification of materials plays an important role in developing and applying triboelectric nanogenerators (TENGs). By exploring the contact electrification phenomena at different interfaces, we can improve the understanding of the ...

Contact Electrification via Redox-Active Molecules. [PDF]

Angew Chem Int Ed Engl
Abstract Contact electrification, as the transfer of charge upon the contact of two (dis)similar materials, is strongly influenced by surface chemistry, which governs the efficiency of charge separation. For harvesting electrical energy from mechanical energy, material pairs with high electron‐transfer efficiency ...

The Charging Events in Contact-Separation Electrification [PDF]

Scientific Reports, 2018
AbstractContact electrification (CE)—charging of surfaces that are contacted and separated, is a common phenomenon, however it is not completely understood yet. Recent studies using surface imaging techniques and chemical analysis revealed a ‘spatial’ bipolar distribution of charges at the nano dimension, which made a paradigm shift in the field ...

The Adhesion‐Enhanced Contact Electrification and Efficiency of Triboelectric Nanogenerators

Macromolecular Materials and Engineering, 2020
In the present work, the contact electrification of polymers that differ in adhesion strength is studied. Electrical current is measured along with adhesion in macroscale contacting‐separation experiments.

Probing Polymer Contact Electrification by Gamma-Ray Radiation

Frontiers in Materials, 2022
Triboelectric Nanogenerators (TENGs) have been regarded as an effective method to solve the energy problem since they were first demonstrated in 2012. Due to their high-power generation and low cost, TENGs have been widely applied in the fields of energy,

Quantifying and understanding the triboelectric series of inorganic non-metallic materials

Nature Communications, 2020
The mechanism of contact electrification remains a topic of debate. Here, the authors present a quantitative database of the triboelectric charge density and band structure of many inorganic materials, verifying that contact electrification between ...

Contact Electrification Behaviors of Solid–Liquid Interface: Regulation, Mechanisms, and Applications

Advanced Energy & Sustainability Research, 2023
Liquid–solid contact electrification is a universal physical phenomenon. The electrical energy produced by a drop of water during the solid–liquid triboelectric electrification (TE) process is negligible, usually at the level of nA or uA.
