Ellipsometric study of acrylonitrile electropolymerization on nickel

Dynamic mechanical thermal and infrared analyses of polyacrylonitrile ?electrografted? onto a metal

“…2,4 Some of us num electrodes with formation of nonadherent have recently studied the influence of the main polymer films. 1 In contrast, the cathodic reduction experimental parameters : solvent, 4 monomer of some monomers, and particularly acrylonitrile, concentration, 5,6 and reduction potential, on film can lead to the ''grafting'' of organic films, 2 i.e., morphology and thickness. The PAN film and the deposition of films which are permanent even in PAN/metal interface have been investigated by the most powerful spectroscopic techniques available today [4][5][6][7][8][9] : SIMS, ESCA, IR, ellipsometry, copy (UPS), near-edge x-ray absorption fine that occurs before melting (estimated at ca.…”

Voltammetric and amperometric analyses of electrochemical nucleation: electrodeposition of copper on nickel and tantalum

“…Unlike single crystal noble metals [10,56], both the polycrystalline Ni [57,58] and the Ta [59] electrodes used here contain native oxides at their surfaces. However, the Ta surface is likely to contain more native oxides (predominantly Ta 2 O 5 ) than the Ni (NiO) surface [59][60][61]. The native ($30-50…”

Molecule‐to‐Metal Bonds: Electrografting Polymers on Conducting Surfaces

“…[22][23][24][25][26] Although cleanness is obviously necessary to ensure reproducible results, the presence of a metal oxide layer does not preclude formation of an electrografted film, probably because the oxide is reduced or damaged during reductive electrolysis. [27] Classical voltammograms recorded during electrolysis ( Figure 1) exhibit a sharp peak in the cathodic domain, which corresponds to the actual reduction of the vinylic monomers. This peak is clearly of diffusional origin, but its shape is concentration-dependent.…”
