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 ...

On chain models for contact electrification
Journal of Physics: Condensed Matter, 2022 Abstract An exact analytical model of charge dynamics for a chain of atoms with asymmetric hopping terms is presented. Analytic and numeric results are shown to give rise to similar dynamics in both the absence and presence of electron interactions.

Revisiting Contact Electrification at Polymer–Liquid Interfaces
Langmuir, 2022 Contact electrification (CE) occurs naturally at all interfaces between solids and solids, solids and liquids, solids and gasses, and so forth. It has been extensively studied for decades. While CE at a solid-solid interface has been demonstrated to be primarily caused by electron transfer, the underlying mechanism of CE at a liquid-solid interface ...

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 ...
