摘　　要：碳纤维常被作为增强相用以提高水泥基材料的性能,然而碳纤维与水泥基材料的相容性较差。碳纤维表面活性基团少,表现为化学惰性,与水泥基材料的结合仅依靠机械摩擦力。碳纤维表面光滑,与水泥基材料的机械摩擦力小,界面结合较差,从而影响碳纤维效果的发挥。因此,研究者们通过碳纤维表面处理或复掺其他材料对碳纤维/水泥浆体界面进行改善。本文从碳纤维表面氧化、碳纤维表面接枝纳米材料、纳米材料与碳纤维复掺以及聚合物与碳纤维复掺等方面出发,对国内外碳纤维增强水泥基材料界面改性的研究现状进行了总结分析,可为今后碳纤维增强水泥基材料性能的提升提供参考。Carbon fiber is often used as a reinforcement to improve the properties of cement-based material,but the compatibility between carbon fiber and cement-based material is poor.There are few active groups on the surface of carbon fiber,and it shows chemically inert and is bound to cement-based material only by mechanical friction.The surface of carbon fiber is smooth,so the mechanical friction between carbon fiber and cement-based material is small and the interface bonding is poor,which affects the reinforced effect of carbon fiber.Therefore,surface treatment of carbon fiber or mixing other materials are used to improve the carbon fiber/cement interface.In this paper,the research status of interface modification of carbon fiber reinforced cement-based material is reviewed in terms of carbon fiber surface oxidation,carbon fiber surface grafting nanomaterials,nanomaterials mixed with carbon fiber and polymer mixed with carbon fiber,which should provide a reference for the properties im-provement of carbon fiber reinforced cement-based material in the future.
