Shielding Material

In this paper, a novel composite material of Acrylonitrile-Butadlene-Styrene resin (ABS)-based fabric coated with Cu/Ni-P was prepared via chemical redox plating technique. A series of such composite materials with varying thickness of Cu and Ni-P showed remarkable electromagnetic shielding ability. With the increase of Cu thickness, the shielding effect (SE) increased gradually, but leveled off after 1.5μm at a SE of about 70dB. Similarly, with the increase of the depth of Ni-P coats, the SE showed a trendency of gradual increase, and leveled off after 1.0μm at a SE of about 45dB. The optimum ABS/Cu/Ni-P was Cu 1.5μm and Ni-P 1.0μm unilaterally. The ABS/Cu/Ni-P composite material possessed excellent shielding ability in the range of 0.001-1000MHz at a stable SE of >80dB, and it also possessed ideal shielding effect in the range of >36GHz. But in the range of 10-18GHz, the shielding effect is slightly decreased gradually to about 60dB. So the ABS/Cu/Ni-P fabric composite is an ideal candidate for electromagnetic shielding material at low and high frequency radiations.
