摘　　要：未处理的碳纤维表面光滑,具有较强的化学惰性和非极性,与树脂基体间的界面粘结性较差,碳纤维表面的微观形貌结构及化学组成决定了复合材料的性能。对碳纤维表面进行改性,改变碳纤维表面活性及形貌,提高与树脂材料的浸润性,提高界面结合作用,方可将载荷有效地传递给碳纤维,充分发挥碳纤维高强度、高模量等优异性能。介绍了近年国内外碳纤维表面化学组成(引入官能团、接枝分子链等)、微观形貌结构重建改性的研究状况,特别是碳纤维表面构建有机、无机、有机-无机复合微纳米颗粒改性研究的进展,并分析了碳纤维表面改性与结构重建技术研究和应用中存在的一些问题。As the smooth,high chemical inertness and non-polar character of untreated carbon fiber,the interface bonding between resin and carbon fiber was poor,affected mechanical performance of carbon fiber-reinforced composite material.In order to give full play of the high strength,high modulus properties of carbon fiber,surface activity and morphology should be modified for improving the interface bonding and wettability.Carbon fiber surface modification both at home and abroad were discussed,including the research status of surface composition（the introduction of functional groups,graft chain,etc.）and morphology modification.The research progress of carbon fiber surface modified construction of organic,inorganic,organic and inorganic composite nanoparticles was especially introduced,and some problems existing in the carbon fiber surface modification and application were analyzed.
