For continuous production of electromagnetic shielding fabrics, in short time, 3 min., copper, silver, tin and nickel were used to fabricate the coating by magnetron sputtering. By analysis and comparison of depositing rate, dB value and SEM images, the multi-layer displays an inhibition of the electromagnetic shielding effectiveness (ESE), which may resulted from the metal contact potential. It is found that the ESE of the multi-layer rely on the continuity of the bottom layer structure. The bridge-linking of the top layer particles seems lead to the slight increase in particle continuity in the lower layer and hence the ESE of the multi-layer increases somewhat compared to the single silver layer obtained for less time. After the screening experiment, silver has been chosen to fabricate single coating on the PET fabric. The fabric prepared by optimizing parameters has excellent ESE and potential application.
