摘　　要：碳纳米材料是一类具有极大的比表面积、优异的力学性能、热稳定性与导电性能的功能性材料。在过去二十年中,这类材料已经在色谱固定相填料的制备和修饰中发挥着重要作用。随着功能化碳纳米材料制备技术的发展,修饰后的碳纳米管、石墨烯、碳纳米微球以及纳米金刚石等多种功能化碳材料,逐渐被用于提高色谱固定相的耐压性、热稳定性和分离性能。近些年来,超支化碳纳米材料由于具有大量表面活性官能团和可控的层状结构受到色谱工作者的广泛关注。本文综述了近年来以超支化修饰为主的功能化碳纳米材料在色谱固定相填料制备和修饰中的应用,阐述了其中的优点与不足,并对未来功能化碳纳米材料在色谱固定相领域的进一步应用进行展望。Carbon nanomaterials are a kind of functional materials with great specific surface area,excellent mechanical properties,thermal stability and conductive properties. In the past two decades,such materials have played an important role in the preparation and modification of chromatographic stationary phases. With the development of functional carbon nanomaterials preparation technology,a variety of modified carbon nanomaterials including carbon nanotubes,graphene,carbon nanospheres and nano diamond,are gradually applied to improve the pressure resistance,thermal stability and separation performance of stationary phases. Recently, hyperbranched carbon nanomaterials have attracted a wide spread attention from chromatographic researchers,due to its larger number of surface groups and controllable layered structure. In this paper,the applications of hyperbranched carbon nanomaterials in the preparation and modification of chromatographic stationary phase are reviewed. The advantages and disadvantages are described. And the future developments of functional carbon nanomaterials in this field are also prospected.
