Carbonaceous nanomaterials (CNs) with outstanding properties have demonstrated a wide diversity of size-dependent applications. Preparing homogeneous and narrow size distribution of monodispersed CNs is practically laborious and time consuming. Hence, fast fractionation of polydispersed CNs into several monodispersed fractions is of great significance. The size fractionation of CNs could significantly reveal the buried properties that are commonly not observed in the bulk. This review highlights various effective size fractionation techniques of CNs by focusing on their shape and structure and providing the advantages and drawbacks of each technique. Various traditional and instrumental techniques of size fractionation of CNs are discussed. This classification suggests the selection of the best fractionation techniques based on scalability, time, applications and cost effectiveness, as well as the resolution of each technique.

具有出色性能的碳质纳米材料 (CN) 已证明具有广泛的尺寸依赖性应用。制备均匀且尺寸分布窄的单分散 CNs 实际上既费力又费时。因此，将多分散的 CN 快速分馏成几个单分散的馏分具有重要意义。CNs 的尺寸分馏可以显着揭示通常在块体中观察不到的埋藏特性。本综述通过关注 CNs 的形状和结构并提供每种技术的优点和缺点，重点介绍了 CNs 的各种有效尺寸分级技术。讨论了 CNs 尺寸分馏的各种传统和仪器技术。这种分类建议根据可扩展性、时间、
