Surface modification of pyrolyzed carbon fibres by cyclic voltammetry and their characterization with XPS and dye adsorption

Carbonaceous materials have been obtained by pyrolysis of composites based on olive stones biomass, novolac resin as binding agent, with or without an aromatic compound (naphthalene). The pyrolysis residue at 1000 °C is 40 w% and its electrical conductivity, σ, is 0.13 S/cm. Small cylindrical specimens have been manufactured and pyrolyzed at 1000 °C in order to be used as electrodes. Platinum was electrodeposited by cyclic voltammetry on these specimens using them as working electrodes or on commercial carbon fibres, respectively, for correlating purposes. The morphology of both carbon materials, used as electrodes, was characterized by SEM images and the presence of Pt was determined based on EDS analysis. The crystallographic planes of Pt–carbon of Pt deposited on carbon materials were characterized with XRD. The oxidation of ethanol from a proper solution using the carbonaceous specimen and the carbon fibres as working electrodes was examined by cyclic voltammetry.

Electrochemical Pretreatment

This work demonstrates the efficacy in performing an electrochemical pretreatment on carbon fibres to improve the effect of plasma polymerization of acrylic acid on these surfaces. Modified samples demonstrated improve physical properties including tensile strength and Young’s modulus, as well as an increase in composite performance as measured by the interfacial shear strength. The electrochemical pretreatment was shown to enhance the advantages observed when coating fibres using plasma polymerization.
