“…This XPS analysis leads to determine the oxidation degree of plasma-PANi by comparison with N1s XPS spectra of chemical PANi in its different oxidation states, presented in Fig. 5c [39]. The completely reduced form, leucoemeraldine base (LB) presents a great majority of amine species.…”

The polymerization of aniline under continuous and pulsed RF-plasma conditions is studied using the same plasma reactor. The effects of input power, on and offtimes, frequency and duty cycle variations on the growth kinetics and on the chemical structure of the obtained layers are examined. The chemical structure of the films is characterized using Fourier Transform Infra-Red, X-ray photoelectron and UltraVioletVisible spectroscopies. The thickness of the films is determined by profilometry. The results show a strong dependence of film chemistry and deposition rates on the discharge power and on-time. The film deposited by pulsed plasma grows mainly during the plasmaon period. Furthermore, this work shows that the retention of aromatic rings can be evaluated by Fourier transform infrared analysis whereas oxidation degree of plasma polyaniline can be determined by X-ray photoelectron and UV-Vis spectroscopies.

“…Its origin is the reduction of nitro groups of 4-NTP molecules at the GC surface under the X-rays beam during XPS measurements [31]. The peak with the binding energy of 401.2 eV is assigned to a hydroxylamino group (NHOH) or positively charged nitrogen [25,32]. Fig.…”

“…The highest one, located at 291.2 eV, is ascribed to the strong polarized C-N + bonding of the EpiCure W segments in the nanocomposites. The signals of the C-N component at a binding energy of 285.5 eV [38] cannot be resolved unambiguously in the C1s core-level spectrum when using Mg Kα excitation [42].…”

Epoxy resin nanocomposites reinforced with three different ionic liquid functionalized carbon nanotubes (f-CNTs) were fabricated by an in situ polymerization method. The influence of the anions on the curing process was studied through differential scanning calorimetry (DSC) and normalized Fourier transform infrared (FTIR) spectroscopy. The composition of the nanocomposites was analyzed by X-ray photoelectron spectroscopy. Two different mechanisms are proposed to explain the curing process of the neat epoxy and its composites. The electric conductivity and mechanical properties of the nanocomposites are also reported. The tensile strength was increased dramatically due to the insertion of f-CNTs. Scanning electron microsopy fracture surface analysis indicates a strong interfacial bonding between the carbon nanotubes and the polymer matrix.
