摘　　要：采用造纸湿法成形技术制备了一种单壁碳纳米管(SWCNT)/芳纶纤维(AFs)纸基复合材料(PBCs)。研究了SWCNT添加量对PBCs导电性能和介电性能的影响;基于PBCs复介电常数,仿真模拟了8-12GHz蜂窝结构的反射率,并与实测值进行对比。结果表明,SWCNT在极低载量下即可实现对PBCs电导率和复介电常数的宽范围调控,是一种有潜力的电磁波吸收材料。A singlewalled carbon nanotube(SWCNT)/aramid fibrid(AF)paperbased composites(PBCs)were prepared by traditional wet forming technologyThe effect of SWCNT addition on the conductivity and dielectric properties of PBCs was studiedBased on the complex dielectric constant of PBCs,the reflectivity of 812GHz honeycomb structures was simulated and compared with the measured valuesThe results indicate that SWCNT can achieve wide range regulation of the conductivity and complex dielectric constant of PBCs under extremely low load conditions.
