Embodiment 1
[0030] (1) A commercially available aramid paper substrate with a thickness of 0.18 mm was cut into a size of 5 cm×5 cm, soaked in a 50% ethanol solution, washed for 30 minutes, taken out and dried.
[0031] (2) The cleaned aramid paper substrate is subjected to normal temperature plasma treatment under the conditions that the nozzle height is 4 cm, the nozzle speed is 1 m / min, and the duty ratio is 80%.
[0032] (3) Put the plasma-treated aramid paper substrate into the silver nitrate solution with a concentration of 20g / L prepared in advance, after soaking for 30min, slowly drop the glucose solution with a concentration of 30g / L into the silver nitrate solution In the solution, after the reaction was carried out for 24 hours, the aramid paper substrate was taken out, washed with deionized water for 3 times, and then vacuum-dried at a temperature of 60° C. for 24 hours to obtain silver-plated conductive aramid paper.
