This article reviews the available literature published to date on the reinforcement of metals with carbon-nanofillers (CNTs and graphene), and also offers a specific focus on issues related to the mechanical and tribological properties of nanocomposites. Carbon-nanofillers (later denoted by C-nanofillers) are known to have extraordinary mechanical properties and multifaceted characteristics and are ideal candidates for the reinforcement of metals for numerous applications. However, their incorporation for practical applications has been challenging researchers for decades. The most important issue is uniform dispersion due to sizeable surface differences between carbon-nanofillers and metals. Other concerns are structural integrity, wetting with metals, and interfacial connections. Nanocomposite applications can only be effective when these challenges are properly addressed and overcome.

碳纳米管和石墨烯增强金属纳米复合材料的分散和增强作用的最新研究进展

本文回顾了迄今为止发表的有关用碳纳米填料（CNT和石墨烯）增强金属的现有文献，并且特别关注了与纳米复合材料的机械和摩擦学特性有关的问题。碳纳米纤维（后来用C-纳米纤维表示）具有非凡的机械性能和多方面的特性，是用于多种应用的金属增强的理想选择。然而，数十年来，将它们结合到实际应用中一直对研究人员构成挑战。最重要的问题是由于碳纳米粉与金属之间的巨大表面差异而导致的均匀分散。其他问题包括结构完整性，金属润湿和界面连接。
