Example Embodiment

[0027] Example 1.

[0028] Such as figure 1 Shown is a method for preparing electroless nickel-plated conductive film on the surface of polymer film, using 2×5cm 2 , 120m thick polyethylene terephthalate (PET) film as the base material, immersed in 30g / L NaOH solution at 60℃ for 30min, washed with water, and immersed in 0.5g / L containing 10g / L stannous chloride Palladium chloride, 20g / L 37% hydrochloric acid solution for 1 min, washed with water, immersed in 20g / L hydrochloric acid solution for 1 minute, washed with water to complete the pre-treatment and pretreatment. Then it was immersed in a 80°C bath for 1 min. The bath formulation was nickel chloride 25g / L, sodium hypophosphite 15g / L, sodium citrate 120g / L, ammonium chloride 40g / L, and pH 9. A nickel-plated PET conductive film was obtained, the thickness of the coating was about 1 μm, and the coating was dense under microscope observation.

Example Embodiment

[0029] Example 2.

[0030] Such as figure 1 Shown is a method for preparing electroless nickel-plated conductive film on the surface of polymer film, using 2×5cm 2 , A polyethylene terephthalate (PET) film with a thickness of 120 μm was used as the substrate, and the pretreatment and pretreatment were completed as in Example 1. Then immerse in a 45°C bath for 10 min. The difference is that the bath formulation is nickel sulfate 45g / L, sodium hypophosphite 30g / L, sodium pyrophosphate 50g / L, triethanolamine 15g / L, and pH 9.5. The nickel-plated PET conductive film was obtained, and the thickness of the plating layer was about 5 μm. The plating layer was dense under microscope observation.

Example Embodiment

[0031] Example 3.

[0032] Such as figure 1 Shown is a method for preparing electroless nickel-plated conductive film on the surface of polymer film, using 2×5cm 2 , A polyethylene terephthalate (PET) film with a thickness of 120 μm was used as the substrate, and the pretreatment and pretreatment were completed as in Example 1. Then immerse in the 85℃ plating bath for 1.5min, the difference is that the bath formulation is nickel chloride 25g / L, sodium hypophosphite 15g / L, sodium glycolate 60g / L, lead nitrate 0.001g / L, 12 Sodium alkyl sulfate 0.02g / L, pH value 5. A nickel-plated PET conductive film was obtained, and the thickness of the plating layer was about 2 μm. The plating layer was dense under microscope observation.

Abstract

The invention discloses a chemical plating nickel conductive film on polymer thin film surface and method for preparing the same, wherein the conductive film is prepared through the steps of, (1) a pretreatment step of cleaning the surface of the polymer film, (2) carrying out activating and/or sensitization to the polymer film obtained in steps (1), water scrubbing for use later, throwing the polymer film obtained in step (2) into chemical plating liquid, water scrubbing for use later, (4) drying and heat treatment at 120-220 deg. C.

Description

technical field [0001] The invention relates to a conductive film obtained by attaching a layer of metal coating on the surface of a polymer film and a preparation process thereof, in particular to a conductive film obtained by plating nickel on the surface of a polymer and a preparation process thereof, and belongs to the technical field of chemical plating. Background technique [0002] With the widespread use of electronic and electrical products, while bringing convenience to people's lives, it also brings about the problem of electromagnetic pollution. These electromagnetic pollution often cause greater interference to other electronic equipment, and also affect people's health. . At the same time, in the military, the shielding of radar waves is an important part of military equipment stealth. Existing shielding materials often directly use metal sheets, metal mesh, etc., which have a problem of large specific weight, which limits the application in some areas that re...
