Double layer (surface science) - Wikipedia
In surface science, a double layer (DL, also called an electrical double layer, EDL) is a structure that appears on the surface of an object when it is exposed to a fluid. The object might be a solid particle, a gas bubble , a liquid droplet , or a porous body .
"Electrostatic Double Layer Repulsion" : for charged particles, this force arises from a diffuse, highly mobile surface layer of counterions; an exponential repulsion exists
What is an Electric Double Layer? – Gebbie Lab – UW–Madison
2023年6月21日 · This gives rise to a structuring of ions called the electric double layer (EDL), a model which describes how ions arrange themselves in solution under applied potential (Figure 5). The EDL is essentially a wall of ions that surrounds the surface in a way that balances its charge and screens the potential from the surface.
How to Assess and Predict Electrical Double Layer Properties ...
2024年11月11日 · The electrical double layer (EDL) is an interfacial region between an electronic conductor (electrode) and an ionic conductor (electrolyte) that is an intrinsic part of any electrochemical system. The electrode potential is the main control parameter that affects the distribution of species and charges at the electrode/electrolyte interface.
Double layer forces - Wikipedia
Double layer forces occur between charged objects across liquids, typically water. This force acts over distances that are comparable to the Debye length, which is on the order of one to a few tenths of nanometers.
Electrical double layer | Capacitance, Electrolytes, Adsorption ...
Electrical double layer, region of molecular dimension at the boundary of two substances across which an electrical field exists. The substances must each contain electrically charged particles, such as electrons, ions, or molecules with a separation of electrical charges (polar molecules).
Electric Double Layer - an overview | ScienceDirect Topics
2012年4月4日 · An electric double layer refers to the region at the interface between an electrode and an electrolyte, where charged ions accumulate, creating a significant electric potential difference across it. This phenomenon is crucial in battery recycling and supercapacitor operation for energy storage.
The Electrical Double Layer and Its Structure | SpringerLink
2009年1月1日 · At any electrode immersed in an electrolyte solution, a specific interfacial region is formed. This region is called the double layer. The electrical properties of such a layer are important, since they significantly affect the electrochemical measurements.
Electric Double Layer - an overview | ScienceDirect Topics
At the interface between a charged electrode and a (liquid) electrolyte, electrons, ions and solvent molecules form a structure that is typically referred to as the electric double layer. The structure of this double layer has a direct impact on capacitive energy storage and can influence (the rate of) electrochemical reactions.
