碳纤维表面改性及其对碳纤维/树脂界面影响的研究进展

碳纤维具有优异的性能,常用于树脂基体的增强。然而,碳纤维表面具有疏水性和化学惰性,导致其与树脂基体间的界面粘结性较差,因此,有必要对碳纤维进行表面改性。综述了近几年国内外碳纤维表面改性方法的研究进展,以及这些改性方法对碳纤维与树脂基体界面性能的影响,并将这些表面改性方法分为湿化学法改性、干法改性、纳米材料改性三大类,具体的改性方法包括上浆剂改性、等离子体改性、纳米粒子改性等,并对纳米材料改性作了较详细的介绍,希望能为碳纤维表面改性提供一些帮助。

Carbon Fibers Surface Modification and Effects on the Interfaces Between Fibers and Resin Matrices:A Review

Carbon fibers (CF) are used as a reinforcement of polymer composites due to excellent performance. However, carbon fibers are hydrophobic and chemical inertness which cause poor interfaces between CF and resin matrices. Thus, it is necessary to carry out the technology which is used to modify the carbon fibers surface. This paper reviews the research development of carbon fibers surface modification at home and abroad in recent years, and these methods play an important role in carbon fibers and resin matrices. Carbon fibers surface modification are classified into chemical modification, dry modification, nanomaterials modification. Specific modification methods are sizing modification, plasma modification, nanoparticles modification and so forth. At the same time, nanomaterials modification is introduced in detail. The article is expected to provide some valuable help for the modification of CF.
