“…Consequently the exfoliation and dispersion of clay layers can be tailored by the clay and monomer chemistry (Pavlidou & Papaspyrides, 2008). Polyaniline/MMT nanocomposites have been prepared by the insitu polymerization of aniline in the presence of MMT (Olad & Rashidzadeh, 2008). Both unmodified and organomodified MMT were used in the preparation of nanocomposites.…”

“…Clay materials due to their platelet structure and high aspect ratio, in well dispersed state, decrease the permeability of polymer coating films by increasing the diffusion pathways such as shown in figure 9. The nanocomposite of various polymeric materials such as polystyrene, poly (styrene-coacrylonitrile), polyaniline, polypyrrole, polysulfone, polyacryltes, polyimide and epoxy with unmodified and organically modified clays have been investigated as anticorrosive coatings on metals (Yeh et al, 2008;Olad & Rashidzadeh, 2008). According to our results obtained by electrochemical tafel slope analysis, the corrosion current of iron samples coated by the 100 μm thickness of polyaniline/MMT coating is more lower than that of samples coated by pure polyaniline coating with the same thickness in various corrosive environments (Olad & Rashidzadeh, 2008).…”

“…Therefore, for PANI/EP composite coated steel, it is considered that the greatly improved corrosion protective efficiency of the steel was derived from the good barrier, passivation and electric field effects of PANI. In addition, the improvement of the adhesion, mechanical and barrier effects of coatings are also necessary to enhance their efficiency in corrosion protective properties [36]. Because of PANI fillers dispersed in epoxy coating, Chen et al [37] have confirmed that the PANI containing coating had higher adhesion and mechanical effects than the pure epoxy coating.…”

Conducting polymers represent a promising application prospect in the field of metal corrosion control. In this investigation, poly(o-toluidine) (POT)/nano zirconium dioxide (ZrO 2 ) composite were prepared by in situ polymerization of o-toluidine monomer in the presence of nano ZrO 2 particles. Fourier transformation infrared spectroscopy, UV-visible spectroscopy, X-ray diffraction and Scanning electron microscopy were used to characterize the composition and the structure of the composite. POT/nano ZrO 2 composite was mixed with epoxy resin (EP) through a solution blending method and the three components POT/ nano ZrO 2 /epoxy composite coating was coated onto the surface of steel coupon, and its corrosion protective efficiency was studied by electrochemical measurements and immersion test in 3.5 % NaCl solution as corrosion environment and also compared with that of POT/epoxy composite coated steel, polyaniline (PANI)/epoxy composite coated steel and pure epoxy coated steel. According to the results, POT/nano ZrO 2 /epoxy composite coated steel has got higher corrosion resistance than that of POT/epoxy composite coated steel and PANI/epoxy composite coated steel. It was found that POT powders dispersed in the epoxy and polyamide system improved the barrier and electrochemical protection properties of epoxy coating and the addition of nano ZrO 2 particles increased the tortuosity of the diffusion pathway of corrosion substances.
