研究了聚丙烯腈基碳纤维（PAN）经氧化处理后表面官能团与其在空气中的电化学行为的关系。采用X射线光电子能谱（XPS）分析了碳纤维表面的化学性质，并利用电化学装置研究了处理后碳纤维在硫酸铜电镀液中的电化学行为。采用场发射扫描电子显微镜（FESEM）研究了官能团对铜镀层形貌的影响。结果表明，当氧化温度提高到400 ℃时，O/C原子比从23.05%（原始碳纤维）迅速上升到42.83%，-C=O含量最高。碳纤维表面官能团的种类和浓度与碳纤维在硫酸铜镀液中的电化学行为有密切关系。结果表明，铜电沉积是外加电压和表面官能团还原的共同作用。随着官能团的增加，Cu晶核的数量增加，进而影响沉积Cu的形貌。(c)2010 Elsevier B.

The relationship between surface functional groups and electrochemical behaviors of polyacrylonitrile (PAN)-based carbon fibers (CFs) differentiated by oxidation treatment in air was studied. The chemical character of the CFs surface was estimated by X-ray photoelectron spectroscopy (XPS) and the electrochemical behavior of treated CFs in CuSO4 plating solution was studied by electrochemical setup. The influence of functional groups on the morphology of copper deposits was characterized by field-emission scanning electron microscopy (FESEM). It was found that the O/C atomic ratio rose rapidly from 23.05% (as-received carbon fibers) to 42.83% as the oxidation temperature was increased to 400 degrees C and the content of -C=O was the highest. Concentrations and types of the functional groups on CFs surface showed a close connection with the electrochemical response of CFs in CuSO4 plating bath. It was showed that Cu electrodeposition was the interaction of applied voltage and the reduction of surface functional groups. With the functional groups increased, the quantities of the Cu nuclei increased, further the morphology of deposited Cu was affected. (c) 2010 Elsevier B.V. All rights reserved.
