Embodiment 1
[0032] A preparation method of nanocomposite conductive coating. (1): Place 150 mL of concentrated sulfuric acid with a mass fraction of 98% and 150 mL of concentrated nitric acid with a mass fraction of 69% in a 500 mL three-necked flask, add 8 g of carbon nanotubes, and then place it in a water bath, under the condition of condensation and reflux The mixture was heated to 80°C and stirred at this temperature for 4 h; the obtained mixture was suction filtered and washed with distilled water for several times until the pH of the filtrate was neutral. The obtained product was dried in an oven at 60°C for 24h, then ground and sieved to obtain modified carbon nanotubes;
[0033] (2): First, add 2 g of modified carbon nanotubes to the three-necked flask; then, add 200 mL of hydrochloric acid solution with a concentration of 1 mol / L to the three-necked flask; finally, add 18 g of aniline to the three-necked flask; The solution system in the three-necked flask obtained by the above...
