Abstract
An electromagnetic shielding material was prepared by adding stainless steel fiber and nickel powder into low density polyethylene. The effects of adding stainless steel fibers on the electromagnetic shielding as well as on the electrical and mechanical properties of the composite are studied. The results showed that the material's shielding efficiency is 25-30 dB (f < 800 MHz), and the percolation threshold is 15%-20%. It can absorb electromagnetic wave because of its magnetism and electric wastage of the stainless steel fiber. The material attains its highest tensile strength when the content of nickel powder and stainless steel fiber reaches 16%.
