Contact Electrification via Redox‐Active Molecules [PDF]

open access: yesAngewandte Chemie International Edition
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 ...
