“…The spectrum (a) refers to CF electrode with a profile graphite-like material [26,27] , showing two bands: D (~1352 cm −1 ), G (~1582 cm −1 ). Nonetheless, the spectrum (a) is compatible with PAN-based CF, i.e., it is the structure of the carbon fibers obtained from polyacrylonitrile precursor graphitized at temperatures around 1000 °C [27][28][29] , as expected. For all composites analyzed, the spectra are dominated by the PAni spectrum and exhibit characteristic bands of conducting species, mainly CF/PAni-30.…”

SbstractCarbon fiber/polyaniline composites (CF/PAni) were synthesized at three different deposition time of 30, 60 and 90 min by oxidative polymerization. The composite materials were morphologically and physically characterized by scanning electron microscopy and by Raman spectroscopy, respectively. Their electrochemical responses were analyzed by cyclic voltammetry, by galvanostatic test, and by electrochemical impedance spectroscopy. The influence of the PAni layer thickness deposited on carbon fibers for the composite formation as well as for their electrochemical properties was discussed. The CF/PAni-30 showed a nanometric thickness with more homogeneous morphology compared to those formed in deposition times of 60 and 90 min. It also showed, from the electrochemical impedance spectroscopy measurements, the lowest charge transfer resistance value associated to the its highest value for the double-layer capacitance of 180 Fg -1 making it a very strong candidate as a supercapacitor electrode.

The characterization of carbon fibres by x-ray photoelectron spectroscopy depends on several experimental and theoretical aspects that noticeably improve the accuracy of the analysis when properly taken into account. Tbese aspects are briefly discussed in the light of the most representative literature available. Attention is focused on points that need a deeper understanding and suggestions are given about possible analysis strategies.

Careful curve fitting is needed when using XPS to investigate oxidized functional groups on carbon-fibre surfaces. This is important because the core regions often contain a number of overlapping features some of which are of low intensity, and the C Is region is influenced by an asymmetric graphitic feature. The fitting approach used requires that the same content of oxygenated species must be obtained from both the C 1s and 0 Is regions. The approach is used to analyse untreated fibres before and after cleaning.
