ln this study, 3D-free polyester fiber nickel electrodes to explore the fabric of the 3D structure for the electromagnetic wave absorption efficiency, and make changes in its external conditions, to change its non-nickel-plated electrodes of time, this experiment provided in accordance with Reference Electrode Nickel-plated method fixed pH value of 4 to 6, the ternperature is fixed at 90 degrees, the time set for 5 minutes, 10 minutes, 15 minutes, 20 minutes, 25 minutes, sequentially to increase their time to observe its time to change for the electromagnetic wave absorption efficiency influence, hoping to find the best possible absorption of the fàbric of its 3D temperature conditions, and thus can enhance the absorption of electromagnetic waves effect, this experiment, absorption of electromagnetic waves up to 27dB.
