Thermosensitive conducting composite particles were synthesized using the unsulfonated P(St-NIPAm) as a thermosensitive substrate. A series of characterizations have been performed to study the effects of thermosensitive PANI@poly (St-NIPAm) conductivity performance. Aniline diffused into P(St-NIPAm) particles in solution, and then polyaniline (PANI) was in-situ produced in P(St-NIPAm) particles through oxidation polymerization. The samples showed different particle sizes at different temperatures. The content of conducting polyaniline is dependent on NIPAm feed ratios. The particle electrical conductivity was improved with the increasing NIPAM feed ratios and exhibited thermal responsive electrical conductivity. The thermosensitive conducting composite particles will have wide applications in sensors, for example, they could be used to fabricate smart conductive gel responsive to temperature and moisture.

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.

Conducting polyaniline / ZnO nano composites are synthesizedusing a simplified cheap method with one step in –situ chemicalpolymerization, and AC conductivity (σac) of the prepared samples isstudied in the range of frequency from 50 Hz to 15MHz.). Thepresence of polarons in the conjugated polymer chain are responsiblefor the ac conductivity is reliance on the frequency in thesecomposites. The effect of increasing the ZnO nano particleconcentration irradiation and gamma radiation on the electricconductivity was analyzed. The result showed that thenanocomposite prepared has the highest conductivity, from purepolyaniline and the exponential factor S was found increasing withZnO content it was 0.739 for PANI pure and for 0.02 ZnO it was1.415.
