To obtain high performance of electromagnetic shielding materials, the polymer and carbon nanotube (CNT) nanocomposites combining with additional ferromagenetic particles were developed and their performance and characterization were investigated. For the developed materials, the high Shielding effective (SE) achieved was close to 35 dB for CNT/SMP composites. Nanocomposite fibers containing CNT and cobalt ferrite (CoFe2O4) nanoparticles were fabricated by electrospinning. The nanofibers exhibited effective SE. The mechanism of SE is investigated and will provide hints for innovative electromagnetic material design. All these results showed the developed materials can be expected for wide uses in industry.
