WebNov 1, 2016 · Electric double layer 1. Introduction Spherical polyelectrolyte (PE) brushes (SPEB) refer to a system of PE brushes grafted on a spherical core [1], [2], [3]. PE brushes represent a special case of PEs (or charge containing polymers) localized at an interface (a solid-liquid or a polymer-liquid interface). WebJan 1, 2009 · 1 Introduction. 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. In an electrical circuit used to measure the current that flows at a ...
