In this paper, four composite coatings of nano-SnS/polyvinylbutyral (PVB), nano-MoS2/PVB, nano-SnS-Zn/PVB, and nano-MoS2-Zn/PVB were prepared, and their anti-corrosion mechanism was analyzed by experimental and theoretical calculations. The results of the electrochemical experiments show that the effect of nano-MoS2 on the corrosion protection performance of PVB coating is better than that of nano-SnS in 3% NaCl solution, and that the addition of Zn further enhances this effect, which is consistent with the results of weight loss measurements. Furthermore, the observation of the corrosion matrix by the field emission scanning electron microscope (FESEM) further confirmed the above conclusion. At last, the molecular dynamics (MD) simulation were carried out to investigate the anti-corrosion mechanism of the nanofillers/PVB composites for the copper surface. The results show that both nano-SnS and nano-MoS2 are adsorbed strongly on the copper surface, and the binding energy of nano-MoS2 is larger than that of nano-SnS.

“…stated that TiO 2 reduces the pores of the polymer in the polypyrrole‐TiO 2 composite that they synthesize via galvanostatic method in oxalic acid solution. Composites formed by conductive polymers and inorganic nanoparticles are quite remarkable due to their synergistic and complementary effects . Electronic, optical, photoelectrochemical, thermal and corrosion protective properties of polyaniline can be improved with some nanoparticles such as SiO 2 , TiO 2 and carbon nanotubes .…”

film was synthesized in 0.30 M oxalic acid solutions containing 0.05 M aniline + 0.05 M pyrrole + 0.05 M N-methylpyrrole. Poly(aniline-co-pyrrole-co-N-methylpyrrole)-TiO 2 nanocomposites were synthesized in 0.30 M oxalic acid solutions containing 0.05 M aniline + 0.05 M pyrrole + 0.05 M N-methylpyrrole + 0.1/0.4/1.0 gL À 1 TiO 2 .Electrochemical syntheses were performed on the carbon steel (CS) elctrode using cyclic voltammetry technique. The terpolymer and nanocomposites were characterized by SEM, EDX, electrochemical impedance spectroscopy (EIS), open circuit potential-time and anodic polarization techniques. Nanocomposite structures were observed after the addition of TiO 2 nanoparticles into terpol-ymer films and these results was verified via EDX analysis. The results driven by EIS and anodic polarization suggest that, terpolymer and nanocomposite coated electrodes have been shown to have a protective effect against the corrosion of the CS electrode. The nanocomposite coated electrode synthesized in an environment containing 0.4 gL À 1 TiO 2 was found to have higher corrosion resistance in comparison to uncoated electrode, terpolymer coated electrode and electrodes coated with nanocomposites that is synthesized in environments containing 0.1/1.0 gL À 1 TiO 2 . These results showed that the amount of TiO 2 affects the anticorrosive properties of the synthesized nanocomposite.

“…İnorganik malzeme olarak tabakalı silikatlar ve organik malzemeler olan iletken polimerlerin kimyasal veya elektrokimyasal yöntemlerle bir araya getirilmesi ile hazırlanan iletken nanokompozitler, bileşenlerinin tek başına gösterdikleri özelliklerden daha gelişmiş yeni özellikler gösterdikleri için, son yıllarda ilgi çeken yeni bir malzeme sınıfını oluşturmuştur [1,2] [14].

The conductive composite material obtained by using a conductive polymer and an inorganic layered clay. • The increase of microhardness in the composite material with the help of synergetic effects of its components. • The rise of thermal stability in POA polymer after the incorporation of talc to the composite material. Purpose: The purpose of the research is to prepare a conductive POA/talc composite using conducting poly(oanisidine) and layered talc clay in the presence of ammonium persulfate as oxidant. After preparation of the composite a new material with improved properties such as elastic-plastic property and thermal properties was obtained. Theory and Methods: Conductive POA/Talc composite was prepared via the chemical polymerization of o-anisidine in the presence of talc particles by using ammonium persulfate as oxidant. 1.0 M aqueous HCl solution (17 mL) was first added onto talc (1.0±0.001 g) and o-anisidine in a beaker and then the suspension was mixed for about 15 min. The polymerization was initiated by the addition of aqueous acidic oxidant solution (3 mL) into the mixture. After 2 hours of the polymerization, the mixture was first separated by centrifugation at 1000 rpm and then washed by distilled water, methyl alcohol and dilute HCl solution, in sequence, to remove unreacted monomer and oxidant from the composite, as well as to recover dopant anions. As the final step, the composite was dried at 50 o C for 24 h under vacuum. Results: The polymerization parameters such as the effect of APS/o-anisidine mole ratio and the effect of o-anisidine concentration on the conductivity and POA amount of the POA/talc composite were investigated. The structural, morphological and thermal properties of the composite were analyzed by using XRD (X-ray Diffraction), FTIR (Fourier Transform InfraRed spectroscopy) and TGA (Thermogravimetric Analysis) techniques; micro-hardness measurement, BET (Brunauer-Emmett-Teller) surface area analysis and SEM (Scanning Electron Microscopy) analyses. TGA showed that the thermal stability of the conducting polymer POA increased by the formation of the composite structure with talc clay. Conclusion: A POA/talc composite with a POA content of 42.7% and a conductivity of 3.2x10-5 S/cm was obtained through the polymerization conditions of 0.2 M o-anisidine concentration, 1,5 APS/o-anisidin mole ratio and 0.1 M HCl concentration over 2 hours at 20 o C. Micro-indentation analysis indicated that the micro-hardness property of the talc particles increased after the addition of the conducting polymer to the composite. The coating of the conducting POA polymer on the talc surfaces was confirmed by the stable places of the peaks in the XRD patterns and the micrographics in SEM microstructures.
