Source publication
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 partic...

... as the parent porous MIL-101 throughout the synthetic procedure, while the the polyaniline sample was, as expected, amorphous at the similar synthetic conditions (Fig. 1). The scanning electron microscopy (SEM) images also confirm that polyaniline@MIL composite sample retain the crystalline morphology of MIL-101, unlike free polyaniline sample (Fig. 2). More importantly, no free amorphous polyaniline was found on the surface of MIL-101 crystals, which suggests that the polymerization of the aniline took place predominantly inside the MIL ...

We investigated current-voltage (I-V) characteristics of bulk polyaniline and aniline polymerized inside nanopores of chromium terephthalate dielectric matrix MIL-101. The temperature dependence of electrical conductivity σ(T) of these materials are described by the fluctuation-induced tunneling model (FIT), which means that the main contribution t...
