The interface between the polymer and the filler particles influences the properties of dielectric materials. To understand how interfaces act, they should be considered as layers rather than interfaces. Therefore the term interphase is more appropriate for the polymer layer around a filler particle where the polymer chains are chemically and/or physically bound to the particle surface.<br>The interphase is characterized by an ordered polymer structure around the particles. This paper discusses the influence of the ordered polymer structure around the particles on the polymer properties with regard to explain the effect of nano particles on material properties.<br>In this paper also a model is given how to estimate the maximum interphase fraction depending on particle diameter and interphase thickness. It is postulated that the most significant results can be achieved at this maximum.
