Electrical Conductivity of Nanodimensional Polyaniline Particles in Nanoporous Dielectric Matrix of MIL-101

Abstract:

We investigated an electrical conductivity of aniline polymerized inside nanopores of chromium terephthalate dielectric matrix MIL-101. We found that temperature dependences of conductivity (T) are described by the fluctuation-induced tunneling model, which means that the main contribution to a net conductivity is caused by contacts between particles of the polyaniline. We also found that the nanoporous matrix affects the composite conductivity via the size reduction of the conducting polyaniline phase encapsulated in the pores. Dependence of conductivity from a current was thoroughly investigated. This dependence is resulted from a reduction of energy gap for current carriers which is, in turn, induced by an increasing electric field applied.
