| Abstract: | The molecular structure of rayon-based carbon fibre surface after electrochemicaloxidation with nitric acid was analyed by X-ray photoelectron spectroscopy (XPS). Theinfluence of factors, current density, electrolyte concentration and oxidation time onsurface structure were investigated. The results indicated that the amount of hydroxylincreased with the increase of current density and oxidation time, and decreased with theincrease of electrolyte concentration. The amount of carboxyl increased with the increase of current density and electrolyte concentrationand decreased with the increase ofoxidation time. The carbonyl increased with the increase of concentration and time anddecreased with the increase of current density. The total oxygen-containing groups increased with the increase of current densety and oxidation time and decreased with theincrease of nitric acid concentration. |
