Embodiment 1

[0036] Such as figure 1 As shown, use 10% sodium hydroxide solution to soak the polyethylene terephthalate substrate for 20 minutes, wash it with deionized water, and dry it for later use. Put aminopropyltriethoxysilane, ethanol and deionized water (the mass ratio of aminopropyltriethoxysilane, ethanol and deionized water is 30:60:10) in a disperser and stir at high speed for 5 minutes to obtain a uniform solution, then add 10g / L copper-silver sulfate solution and continue to stir for 10 min, add 10g / L tetraethyl orthosilicate, use 30% acetic acid to adjust the pH value to 4, continue to stir for 6h, and use ethylene glycol and glycerol to adjust the solution The surface tension of the polyethylene terephthalate base material is less than that of the polyethylene terephthalate substrate, and the activation solution is obtained. The activation solution was selectively printed on the surface of polyethylene terephthalate substrate by doctor blade coating process, and dried at 1...

[0038]Soak the polyvinyl alcohol substrate in 10% sodium hydroxide solution for 20 minutes, wash it with deionized water, and dry it for later use. Put aminopropyltriethoxysilane, ethanol and deionized water (the mass ratio of vinyltriethoxysilane, ethanol and deionized water is 8:60:10) in a disperser and stir at high speed for 5 minutes to obtain a uniform solution , then add 10 g / L ferric chloride solution and continue stirring for 10 min, add 40 g / L tetraethyl titanate, use 10% hydrochloric acid to adjust the pH value to 4, continue stirring for 6 h, and use glycerol to adjust the surface of the solution The tension is smaller than the surface tension of the polyvinyl alcohol base material, and the activation solution is obtained. The activation solution was selectively printed on the surface of the polyvinyl alcohol substrate by a doctor blade coating process, and dried at 80 °C for 10 min. Wash with deionized water, immerse in electroless copper plating solution for pla...

[0040] Soak the nylon substrate in 10% sodium hydroxide solution for 20 minutes, wash it with ionized water, and dry it for later use. Put aminopropyltriethoxysilane, ethanol and deionized water (the mass ratio of aminopropyltriethoxysilane, ethanol and deionized water is 10:60:10) in a disperser and stir at high speed for 5 minutes to obtain a uniform solution, then add 200 g / L zinc nitrate solution and continue stirring for 10 min, add 20 g / L tetraethyl titanate, use 30% citric acid to adjust the pH value to 4, continue stirring for 6 h, and use ethylene glycol and glycerol to adjust the solution The surface tension of the nylon substrate is smaller than that of the nylon substrate, and the activation solution is obtained. The activating solution was selectively printed on the surface of nylon substrate by doctor blade coating process, and dried at 100 °C for 8 min. Wash with deionized water, immerse in electroless copper plating solution for plating, and dry at 60 °C for 2...
