[0018] Example 1 Preparation process of metal patterning on the surface of polyethylene terephthalate (PET) material:
[0019] 1) Cleaning of PET substrate:
[0020] First cut the PET substrate into 1cm×1cm flakes, and soak in lye (sodium hydroxide: 60g / L, anhydrous sodium carbonate: 15g / L, washing powder: 35g / L, and control the temperature of the solution at 65°C) After 10 minutes to remove the grease on the surface, pour out the lye and repeatedly rinse the polymer substrate with distilled water until the pH of the distilled water after rinsing is ≈ 7, indicating that the lye on the surface of the substrate has been rinsed, and then reflux with acetone for 24 hours. After the reflux is completed, ultrasonically clean with toluene, ethanol, and deionized water for 10 minutes, blow dry with nitrogen, and set aside;
[0021] 2) Modification of PET substrate:
[0022] Fix the photomask (copper mesh, line width about 20 μm) with a clip to cover the surface of the PET substrate, place it...

[0032] Example 2 Preparation process of metal patterning on the surface of polyimide (PI) material:
[0033] (1) Cleaning of PI substrate:
[0034] First, cut the PI substrate into 1cm×1cm flakes, use lye (sodium hydroxide: 60g / L, anhydrous sodium carbonate: 15g / L, washing powder: 35g / L, and control the temperature of the solution to 65g / L). ° C) Soak for 10 minutes to remove the grease on the surface. After that, pour out the lye and repeatedly rinse the polymer substrate with distilled water until the pH of the steamed water after rinsing is ≈ 7, which means that the lye on the surface of the substrate has been rinsed, and then use The acetone was refluxed for 24 hours. After the reflux was completed, it was washed with toluene, ethanol, and deionized water by ultrasonic cleaning for 10 minutes, and dried with nitrogen for use.
[0035] (2) Modification of PI substrate:
[0036] Fix the photomask (copper mesh, line width about 20 μm) on the surface of the PI substrate with a c...

[0045] Example 3 Preparation process of metal patterning on the surface of polystyrene (PS) material:
[0046] (1) Cleaning of PS substrate:
[0047] First cut the PS substrate into 1cm×1cm flakes, use lye (sodium hydroxide: 60g / L, anhydrous sodium carbonate: 15g / L, washing powder: 35g / L, and control the temperature of the solution to 65g / L). ° C) Soak for 10 minutes to remove the grease on the surface. After that, pour out the lye and repeatedly rinse the polymer substrate with distilled water until the pH of the steamed water after rinsing is ≈ 7, which means that the lye on the surface of the substrate has been rinsed, and then use The acetone was refluxed for 24 hours. After the reflux was completed, it was washed with toluene, ethanol, and deionized water by ultrasonic cleaning for 10 minutes, and dried with nitrogen for use.
[0048] (2) Modification of PS base material:
[0049] Fix the photomask (copper mesh, line width about 20 μm) on the surface of the PS substrate with a ...
