Composites between carbon fibers (CFs) and heterogeneous materials have been widely studied and their fabrication techniques have been developed. However, their hydrophobic surfaces make it difficult to disperse CFs into hydrophilic resins, which results in weak junctions with ceramics. To develop high-strength composite fibers, it is important to design interfacial chemical bonds. Thus, surface-modification techniques of CFs have recently become the main focus and their interfaces have been characterized by various analytical methods. In this Minireview, various techniques that modify the CF surface by coating with inorganic polymers (metal oxide compounds) are highlighted, and the applications of novel nanocomposite fibers are also described. Furthermore, interfacial bonds between CFs and polymer resins are reviewed and discussed in terms of CF-reinforced plastics and their future prospects.
碳纤维（CFs）与异质材料之间的复合材料已得到广泛研究，其制造技术也不断发展。然而，它们的疏水表面使得碳纤维难以分散到亲水性树脂中，这导致与陶瓷的结合较弱。为了开发高强度复合纤维，设计界面化学键很重要。因此，碳纤维的表面改性技术最近成为主要研究重点，并且其界面已通过各种分析方法进行了表征。在这篇小型综述中，重点介绍了通过用无机聚合物（金属氧化物化合物）涂覆来改性碳纤维表面的各种技术，还描述了新型纳米复合纤维的应用。此外，从碳纤维增强塑料及其未来前景的角度，对碳纤维与聚合物树脂之间的界面键进行了综述和讨论。
