Kurzfassung:
Nanotubular polyaniline (PANI) doped with protonic acids have been synthesized by a “template-free”method. The temperature dependence of resistivity (ρ) and magnetic susceptibility has been studied. The influences of different protonic acids (counterions), doping concentration and the synthesizing concentration of dopant on resistivity also have been investigated. It is obvious from experimental results that ln ρ is linear against T-1/2. With increasing acidity of protonic acids ,doping concentration and the synthesizing concentration of dopant, the resistivity of the samples decreases, and the magnetic susceptibility can be written as a sum of a temperature-independent Pauli spin susceptibility term and a Curie-law term.
