采用过氧化氢在超临界水中对碳纤维进行表面处理，用原子力显微镜观察处理后的碳纤维表面形貌。结果表明，经表面处理后的碳纤维表面粗糙度明显提高。此外，还利用X射线光电子能谱（XPS）对碳纤维表面官能团进行了分析。结果表明，与未处理的碳纤维相比，含氧官能团显著增加。处理后的碳纤维/环氧树脂复合材料的最大层间剪切强度（ILSS）为110.5MPa，高于未处理碳纤维/环氧树脂复合材料的63.5MPa。超临界水中过氧化氢的加入改善了碳纤维/环氧树脂复合材料的界面性能。(C)2009 Elsevier B. V.保留所有权利。
Carbon fibers were treated by hydrogen peroxide in supercritical water and the surface morphologies of treated carbon fibers were observed by atomic force microscopy. It was found that surface roughness of the treated carbon fiber was improved obviously. Furthermore, X-ray photoelectron spectroscopy (XPS) was used to analyze surface functional groups of carbon fibers. It was found that functional groups containing oxygen were significantly increased compared with untreated carbon fibers. The maximal interlaminar shear strength (ILSS) of treated carbon fibers/epoxy resin composite was 110.5 MPa, which was higher than 63.5 MPa for untreated carbon fibers/epoxy resin composite. It also indicated that interface property of carbon fibers/epoxy resin composite was improved by hydrogen peroxide in supercritical water. (C) 2009 Elsevier B.V. All rights reserved.
