Study on shielding effectiveness, electrical conductivity and thermal property of bamboo-plastic shielding composite based on Ni-Fe-P coated bamboo fibers

Herein, we provided a novel bamboo-plastic shielding composite (BPSC) by filling Ni-Fe-P plated bamboo fiber (BF) into HDPE. The Ni-Fe-P coating endowed BF with good conductivity, which thus makes BPSCs possess excellent conductivity, whose resistivity is 4.40 x 10(2)Omega.cm when the filler content is 70 wt%. Besides, an effective shielding effectiveness of 82 dB can be obtained at 0.1-2 GHz, with 70 wt% filing content, and 5 mm thickness of the composite. Results revealed the deposition of Ni-Fe-P alloy metal coating can not only play a role for endowing the BF with excellent electrical conductivity and shielding effectiveness (SE) but also improving the thermal stability of the material.
