Multi-core model for nanodielectrics as fine structures of interaction zones

A multi-core model is proposed as possible fine structures of "interaction zones" to understand various properties and phenomena that polymer nanocomposites exhibit as dielectrics and electrical insulation. An interfacial layer of several tens nm is multi-layered, which consists of a bonded layer, a bound layer, and a loose layer. In addition, the Gouy-Chapman diffuse layer with the Debye shielding length of several tens to 100 nm is superimposed in the interfacial layer to cause a far-field effect. Nanoparticles may interact electrically with the nearest neighbors each other due to this effect, resulting in possible collaborative effect. Such a multi-core model with the far-field effect is discussed to explain various enhanced properties of polymer nanocomposites, and is verified to demonstrate its effectiveness.
