“…To the best of our knowledge, few reports on modified clays as electrodes are available in the literature. In continuation of our work on clay composites [54] as electrode materials, we report here the preparation, characterization and use of MnO 2 /mont K10 composite as electrode material for supercapacitors. The electrochemical properties of MnO 2 /mont K10 composite as obtained were investigated, together with MnO 2 for comparison.…”

“…Bands appeared at (1300, 1375 cm −1 ) are attributed to C-N stretching vibration in the alternate units of quinoidbenzenoid-quinoid rings and C=N + stretching to the quinoid structure respectively (22). The vibration band at (1238 cm −1 ) can be assigned to C-N stretching vibration mode in benzenoid ring (23,24). While the vibrations at (1141, 1111, 1076 and 1037 cm -1 ) are characteristic to C-H bending vibration (25).…”

The polyaniline powder was chemically manufactured by direct oxidation of aniline. The resulting polymer was characterized by the results of optical, measurements by (FT-IR) spectroscopy, we have detected some of the absorption peaks located at 3498, 2858 cm-1, which correspond N-H vibrations, and C-H expansion of the aromatic ring respectively as well as stretching vibrations of quinoid ring have been observed. Structural properties, such as the surface topography using an atomic force microscope (AFM), and Surface composition by (SEM) have been studied. The structure of some pellets of polyaniline powder have been examined by using analytical X-ray diffraction technique, the pattern of observed lines shows a crystalline nature and three large peaks observed.

“…The same trend, with a maximum weight loss in KPAn20, can be observed at the temperature ranges 200-340 and 340-460 C, where the weight loss is due to the removal of dopant and degradation of the PANI chains, respectively. The higher weight loss % of the nanocomposites than pure kaolinite in the temperature range 460-600 C may be attributed to the completion of degradation of the skeletal PANI chain structure beside the dehydroxylation of kaolinite [3]. Table 2 lists the ingredients included in the prepared coating formulations.…”

“…Fabrication of advanced materials from polymer and clay has attracted a lot of research work because of the outstanding properties that make them potential to be used in various applications . Kaolinite is a layered silicate clay of tetrahedral silicate and octahedral aluminate sheets connected with their shared‐oxygens . PANI is the most popular conductive polymer with advantageous properties such as; excellent environmental stability, good electrical conductivity and easily to be chemically synthesized .…”

Kaolinite/polyaniline nanocomposites (KPAns) were prepared by in situ chemical oxidative polymerization. The nanocomposites were synthesized with four different aniline to kaolinite weight percentage; 5, 10, 15, and 20% to produce KPAn5, KPAn10, KPAn15, and KPAn20, respectively. The structural, morphological and thermal properties of the nanocomposites were characterized using Fourier transform infrared, X‐ray diffraction, scanning electron microscope (SEM)–energy dispersive X‐ray analyzer, transmission electron microscope, and Thermogravimetric analysis. The results revealed a very slight increase in the d‐spacing of kaolinite XRD peaks. SEM images showed hexagonal platy sheets of kaolinite crystals that are indistinguishable in KPAn nanocomposites images, especially on using a high amount of polyaniline (PANI). The increase in the percentage of carbon and nitrogen elements in EDAX data proved the adsorption of PANI on the surface of kaolinite platelets. To investigate the anticorrosive performance of the synthesized nanocomposites, kaolinite and KPAn nanocomposites were loaded in various amounts (1, 5, and 9%) in a blend of chlorinated rubber/medium oil alkyd resin (CR/MA) to prepare different formulations that were applied and evaluated as protective coats on steel substrates. Visual corrosion test revealed that 5% KPAn‐loaded CR/MA coats exhibited the best protection against corrosion amongst other formulations as indicated by their lowest degree of rusting and blistering. Potentiodynamic polarization measurements confirmed the highest protection of 5% KPAn10‐loaded CR/MA coat as indicated by the quantitative corrosion rates obtained from Tafel extrapolation. POLYM.
