Conductive polymers had been the topic of the large number of investigations during last decades because of their unique properties such as mechanochemical strength, electrical conductivity, corrosion and thermal stability. Maghnite-H+ is a montmorillonite sheet silicate clay, which exchanged with protons. Polyaniline (PANI), with unique electrical and optical properties, is a promising candidate for wide range of potential applications. So that, in the present paper we report:1

“…The effects of oxidant concentration and reaction temperature on the conductivity of PANI were analysed. PANI dispersions comprising of spherical lattices 5-30 nm size in micellar medium were prepared by Gaspodinova et al [9] with high electrical conductivity and good transparency of the film. Kim et al [10] prepared stable PANI dispersions with 10-20 nm sized particles in SDS micelles and correlated the morphology of PANI with the size and shape of the micelles.…”

For the first time the template synthesis of nano-scale poly(1-naphthylamine) is reported in CSA micellar medium using benzoyl peroxide, ammonium persulphate and potassium dichromate as oxidants. The nanopolymers were characterized by FT-IR, UV-Vis, DSC, TGA, XRD, DLS, as well as SEM techniques. IR spectral investigations revealed the polymerization of 1-naphthylamine through N-C(5) linkages. The UV studies revealed the differences in the chain conformation of the polymers and their polaronic states. The nanosize of the conducting polymers was analyzed by SEM. DLS analysis showed that the particle size of the polymer prepared using the three oxidants varied between 115 and 117 nm. SEM showed that particle size of the three polymers varied between 100 and 312 nm. XRD, as well as DSC analyses confirmed partial crystallinity of these polymers. Conductivity was found to be in the range of 10 −3 to 10 −2 S/cm, which could be correlated to the conformation of the polymeric chains and delocalization of polarons. The nanopolymers were found to be thermally stable up to 400 • C.  Koninklijke Brill NV, Leiden, 2008

“…Among conducting polymers, PAN has been studied most extensively since it has various structures, unique doping mechanism, excellent physical and chemical properties, and good stability, and its raw material can be obtained easily as well [3,4]. PAN is a kind of powder with metallic luster, and the conjugation of its molecule chain is so strong that in a long time it had been considered as a polymer with low solubility, accordingly its application in technology was limited [5]. During the recent few years, the problem of its solubility has been solved effectively through doped with protonic acids [4][5][6].…”

In this paper, we obtained PAN-HCl powder from PAN-EB through doping, prepared PAN/SR composites, and researched the effect of PAN on electrical conductivity and shielding effectiveness (SE) of the composites in order to search new application field of the PAN.…”

With the increasing of electromagnetic pollution and the widely use of commercial and military products, there is an increasing interest in electromagnetic interference (EMI) shielding. This paper mainly aims at electrical conductivity and EMI shielding effectiveness (SE) of the conducting composites made from silicone rubber (SR) with different loading levels of HCl-doped polyaniline (PAN-HCl) in the low frequency range from 3 to 1500 MHz. The result indicates that SE of the composites increase and the volume resistivity decrease with increasing mass ratio loading of PAN-HCl in the SR. The measured SE of the composites are from 16 to 19.3 dB at 100 mass ratio loading of the PAN-HCl and the volume resistivity decrease nine orders of magnitude compared with that of the emeraldine base form of PAN (PAN-EB) composites. q
