Probing Contact Electrification: A Cohesively Sticky Problem

ACS Applied Materials & Interfaces, 2021
Contact electrification and the triboelectric effect are complex processes for mechanical-to-electrical energy conversion, particularly for highly deformable polymers. While generating relatively low power density, contact electrification can occur at the contact-separation interface between nearly any two polymer surfaces.

Contact electrification at semiconductor interfaces: The tribovoltaic effect

MRS bulletin
Contact electrification (CE) (or triboelectrification) is a common phenomenon occurring between any two materials or two states of a material. However, CE in semiconductor materials poses a highly complex problem.

Electric-field-driven interfacial trapping of drifting triboelectric charges via contact electrification

Energy & Environmental Science, 2023
A new facile strategy to maximize the charge density over 1000 μC m−2 for a high-output TENG is demonstrated by introducing new physics in contact electrification, i.e. ‘Electric-field-driven interfacial trapping of drifting triboelectric charges’.

Is Water Necessary for Contact Electrification?

Angewandte Chemie International Edition, 2011
Was Thales right about water? Contrary to previous reports, contact charging can occur in the absence of water. At the same time, water helps stabilize the developed charges. Water???free conditions are realized by performing all experiments and charge measurements under oil???immersion.

Semiconductor Contact‐Electrification‐Dominated Tribovoltaic Effect for Ultrahigh Power Generation

Advances in Materials, 2022
The semiconductor direct‐current triboelectric nanogenerator (SDC‐TENG) based on the tribovoltaic effect is promising for developing a new semiconductor energy technology with high power density. Here, the first SDC‐TENG built using gallium nitride (GaN)

Contact electrification of metals

Journal of Physics D: Applied Physics, 1975
The author has measured the electrostatic charging of two metal bodies which have been brought into contact and then separated. The charge Q is found to be given by Q=C0Vc, where Vc is the contact potential difference and C0 is the 'contact capacitance'.

O2-Independent H2O2 Production via Water-Polymer Contact Electrification.

Environmental Science and Technology, 2023
Hydrogen peroxide (H2O2), as a critical green chemical, has received immense attention in energy and environmental fields. The ability to produce H2O2 in earth-abundant water without relying on low solubility oxygen would be a sustainable and potentially
