摘要：

Ni-coated CNTs (Ni-CNTs) were firstly prepared with a novel electroless plating method assisted with ultrasonic spray atomization, and then silver coated Ni-CNTs(Ni/Ag-CNTs) and copper coated Ni-CNTs(Ni/Cu-CNTs) were prepared by electroless plating and coprecipitation, respectively. The obtained composite powders were characterized by TEM, FESEM and XRD. The Ni-CNTs show continuous and uniform nickel layers on highly dispersed CNTs, and both the Ni/Ag-CNTs and Ni/Cu-CNTs composite powders exhibit the morphology of Ni-CNTs embedded in silver or copper particles. The multi-metal coated CNTs show significant improvement in electromagnetic shielding properties, and the shielding effectiveness of Ni/Ag-CNTs and Ni/Cu-CNTs are 89.34 and 72.21 dB, respectively, which are superior to 55.62 dB of Ni-CNTs.
