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）与异质材料的复合材料已经得到了广泛的研究，其制备技术也已经得到了发展。然而，它们的疏水性表面使得 CFs 很难分散到亲水树脂中，从而导致与陶瓷的结合较弱。为了开发高强度的复合材料纤维，设计界面化学键是很重要的。因此，碳纤维的表面改性技术最近成为了主要的关注点，其界面已经通过各种分析方法进行了表征。在这篇综述中，重点介绍了通过无机聚合物（金属氧化物化合物）涂层来修饰 CF 表面的各种技术，并描述了新型纳米复合材料纤维的应用。此外，还讨论了 CF 与聚合物树脂之间的界面键合，以及在碳纤维增强塑料及其未来前景方面的问题。
