摘要
用X射线光电子能谱(XPS)研究了粘胶基碳纤维在不同电流密度条件下氧化后表面基团的变化规律。结果表明,增加电化学氧化中的电流密度,可以增加碳纤维表面羟基和羟基类基团的数量,羰基的数量则随着电流密度的增加逐渐减少。纤维表面含氧基团总数随着电流密度的增加逐渐增加,达到一定数量后随着电流密度增加含氧基团总数不再明显增加。
The surface groups of rayon - based carbon fibres were analysed by X-ray photoelectron spectroscopy after electrochemical oxidation with nitric acid as electrolyte at different current density. The results indicated that the amount of hydroxyl and carboxyl increased with the increase of current density, but the amount of hydroxyl decreased after a certain current density value was reached. The total amount of oxygen - containing groups increased with the increase of current density.
