| 摘 要： | 研究了碳纤维在无机酸及其相应盐溶液中的循环伏安特性.结果表明,碳纤维在酸性溶液中呈现出最大的双电层充电电流,在碱性溶液中的双电层充电电流较中性溶液中小.碳纤维在酸性溶液中经过电化学氧化可以形成比在碱性和中性溶液中多的表面氧化产物.

| Abstract: | Cyclic voltammograms of carbon fibres in different electrolyte solutions aremeasured. The cyclic voltammo-grams in acid solutions, comprising nitric acid, sulfuric acid and phosphoric acid are different due to the different structures of anions. And those in salt solutions, comprising sodium nitrate,sodium sulfate and sodium phosphate show electrochemical behavior different from relevant acid solutions becauseof different pH values. The charging currents of double electrode layer in acid solutions are higher than in salt solut - ions, which indicates that electrochemical oxidation in acid solutions may produce more oxides on carbon fibre surfaces. |
