We discuss the role of the interlayer region in double walled carbon nanotubes encapsulating fullerenes. We find that electrostatic effects as well as the long range interactions give rise to an increased stability in multiwalled carbon Nanopeapods as compared to the SWNT case. The interlayer state acts as a repository of charge to minimize the electrostatic repulsion. Thus, the number of layers is an important parameter to assess the properties of these systems. The characteristics of similar systems composed of intercalated fullerenes in graphite is also currently investigated.
