摘　　要：水泥基吸波材料可以有效缓解电磁波辐射对人们日常生活的影响.传统吸波剂所制备的水泥基吸波材料因其有效带宽窄、吸波效率低和体积厚重等缺点,限制了其在工程中的应用.与之相比,纳米吸波剂具有量子尺寸效应、宏观量子隧道效应和界面效应等特点,因此纳米吸波剂改性水泥基材料为电磁辐射防护提供了一个新途径.根据纳米吸波剂种类的不同,从碳纳米管水泥基吸波材料、石墨烯水泥基吸波材料和磁性纳米颗粒水泥基吸波材料3个方面总结了国内外相关研究成果,并对未来该领域的发展进行了展望.Cement-based wave absorbing materials can effectively alleviate the impact of electromagnetic radiation in daily life.However,the conventional absorbent cannot be widely used in engineering due to its narrow effective band,low absorption efficiency and heavy mass.Nano-absorbers have the unique characteristics of quantum size effect,macroscopic quantum tunneling effect and interface effect.Therefore,the use of nano-absorbers cement-based modified wave absorbing materials can provide an effective approach for electromagnetic radiation protection.This review summarized recent studies on carbon nanotube cement-based wave absorbing materials,graphene cement-based wave absorbing materials and magnetic nano-metal cement based wave absorbing materials.In addition,the future research direction in this field was also discussed.
