Pure zinc and Zn-MoS 2 composite coatings were prepared by electrodeposition from zinc sulfate-chloride bath containing uniformly dispersed MoS 2 nanoparticles. The effect of MoS 2 on the deposition properties morphology, crystallographic orientation, and corrosion behavior were studied. The electrokinetic properties (zeta potential) and size distribution statistics in plating bath for the particles were evaluated using dynamic light scattering experiments. The Zn and Zn-MoS 2 deposition process was studied by linear polarization and cyclic voltammetry. Scanning electron microscopy, energy dispersive X-ray analysis, X-ray diffraction analysis, and potentiodynamic polarization measurements were used to characterize the coatings. The addition of MoS 2 to the electrolyte significantly changed the microstructure and crystallographic orientation of the zinc deposits and enhanced the corrosion resistance of the coatings. The morphological and electrochemical properties of the zinc coatings were observed to be significantly affected by the incorporation of MoS 2 particles into the zinc matrix.

“…Different CP-TiO 2 composite materials have been prepared both by chemical [13][14][15] and electrochemical [16][17][18][19][20][21] means. These composite materials have been synthesized for different applications: electrochemical actuators [17], corrosion protection [18] and PV cells [13,19,21]. In this study a PAz-TiO 2 composite has been synthesized by electrochemical polymerization of Az in a suspension containing TiO 2 nanoparticles.…”

A poly(azulene)-TiO 2 composite film (PAz-TiO 2 ) was synthesized electrochemically by oxidation of azulene in an electrolyte medium containing TiO 2 nanoparticles. Polymerization was performed under magnetic stirring in an acetonitrile solution containing tetrabutylammonium hexafluorophosphate as the electrolyte salt. Influence of the concentration of TiO 2 in the reaction suspension on the electrochemical and optical properties and on the structure of the composite films was studied by cyclic voltammetry, ex situ Raman and FTIR reflection spectroscopy and in situ UV-vis and FTIR spectroelectrochemical techniques. Morphology of the composite films was studied by Scanning Electron Microscopy and the amount and distribution of the TiO 2 nanoparticles within the polymeric matrix by Inductively Coupled Plasma Mass Spectrometry with laser ablation. Addition of TiO 2 in the reaction suspension had a small catalytic activity for the polymerization of Az. Inclusion of TiO 2 nanoparticles in PAz did not affect the voltammetric behavior or the chemical structure of the formed polymer films. However, a different chain conformation and morphology of the film was formed when synthesized in presence of TiO 2 compared to the plain PAz film. It was also found that the film morphology was more homogeneous when the concentration of TiO 2 was C10 mM in the polymerization solution than films polymerized without any TiO 2 .

“…Recently, UV-induced photoreduction was used for the formation of Pt particle-modified PANI and TiO 2 -PANI composite layers [266]. This turned out to be an effective approach for achieving a homogeneous distribution of small enough metal particles on the CP surface.…”

IntroductionSince the remarkable discovery of high electrical conductivity in polymer materials in 1977 [1], studies on conductive polymers (CP 1 ) have developed into interdisciplinary research expanding in various directions. A significant impetus to the field was given by materials scientists in their attempts to combine the unique properties of conductive polymers with those of other inorganic and organic materials. Thus, in the last two decades, research on the synthesis of CP-based composite materials has flourished and resulted in the development of a great variety of new materials with interesting specifically designed properties. The accumulation of a great number of studies on nanocomposite materials has provoked the recent appearance of several review articles [2-7] attempting to summarize, from different specific points of view, the advances made in the field. Thus, electrochemical aspects [2,7] of CP-based composites, optical and electronic properties [3], polyaniline(PANI)-based nanocomposites [4], the involvement of composites of CPs in chemical sensing [5], and the incorporation of metallocenes in CPs [6] have been extensively discussed.
