Embodiment 1

[0023] The polyethylene terephthalate substrate was soaked in 1mol / L sodium hydroxide at 70°C for 30 minutes, then soaked in 1mol / L acetic acid at 70°C for 15 minutes, then washed with water, and dried in vacuum at 60°C. Dissolve octa(octyloxy)-zinc phthalocyanine in propanol at a concentration of 0.1 g / L. Soak the PDMS stamp in octa(octyloxy)-phthalocyanine zinc ink for 30s, take it out and put it in N 2 Dry in air flow for 30s. Cover the PDMS stamp coated with octa(octyloxy)-zinc phthalocyanine ink on the carboxylated substrate, and press lightly for 5s to transfer the PDMS stamp pattern to the surface of the substrate. Soak the patterned substrate in 0.1g / L PdCl 2 Put in the solution for 10 seconds, take it out and place it in an electroless copper plating solution consisting of 2wt% copper sulfate, 11wt% sodium potassium tartrate, 3wt% sodium hydroxide, 45wt% formaldehyde and 49wt% distilled water for 3 minutes. Exquisite metallic copper patterns can be obtained on the ...

Embodiment 2

[0025] The polyethylene naphthalate substrate was soaked in 3mol / L sodium hydroxide at 70°C for 30 minutes, then soaked in 3mol / L acetic acid at 70°C for 15 minutes, then washed with water, and dried in vacuum at 60°C. Dissolve octa(octyloxy)-zinc phthalocyanine in propanol at a concentration of 1 g / L. Soak the PDMS stamp in octa(octyloxy)-phthalocyanine zinc ink for 30s, take it out and put it in N 2 Dry in air flow for 30s. Cover the PDMS stamp coated with octa(octyloxy)-zinc phthalocyanine ink on the carboxylated substrate, and press lightly for 5s to transfer the PDMS stamp pattern to the surface of the substrate. Soak the patterned substrate in 0.1g / L PdCl 2 In the solution for 10 seconds, take it out and place it in an electroless copper plating solution consisting of 2wt% copper sulfate, 11wt% sodium potassium tartrate, 3wt% sodium hydroxide, 45wt% formaldehyde and 49wt% distilled water for 5 minutes. Exquisite metallic copper patterns can be obtained on the polyethy...

Embodiment 3

[0027] The polyimide substrate was soaked in 5mol / L sodium hydroxide at 70°C for 30min, then soaked in 5mol / L acetic acid at 70°C for 15min, then washed with water, and dried in vacuum at 60°C. Dissolve octa(octyloxy)-zinc phthalocyanine in propanol at a concentration of 0.5 g / L. Soak the PDMS stamp in octa(octyloxy)-phthalocyanine zinc ink for 30s, take it out and put it in N 2 Dry in air flow for 30s. Cover the PDMS stamp coated with octa(octyloxy)-zinc phthalocyanine ink on the carboxylated substrate, and press lightly for 5s to transfer the PDMS stamp pattern to the surface of the substrate. Soak the patterned substrate in 0.1g / L PdCl 2 In the solution for 10 seconds, take it out and place it in an electroless copper plating solution consisting of 2wt% copper sulfate, 11wt% sodium potassium tartrate, 3wt% sodium hydroxide, 45wt% formaldehyde and 49wt% distilled water for 5 minutes. Exquisite metallic copper patterns can be obtained on the polyethylene terephthalate subs...

Abstract

The invention discloses application of a zinc phthalocyanine complex as ink in micro-contact printing. The 2-propyl alcohol solution of 8(Octanohydroxamic)-zinc phthalocyanine serves as micro-contact printing ink; the pattern of a Polydimethylsiloxane (PDMS) seal is transferred to the surface of carboxylation polyethylene terephthalate, polyethylene naphthalate or polyimide substrate; and a delicate metal pattern is obtained on the substrate with a chemical plating method. The application of the zinc phthalocyanine complex as the ink in the micro-contact printing has the beneficial effect that the common phenomena of pattern inflation and pattern torsion in the micro-contact printing can be reduced by the phthalocyanine metal complex ink, and the phthalocyanine metal complex ink has a lowpreparation cost and great potential in the industrial application and is stable.

Description

technical field [0001] The invention belongs to the field of modern electronic technology, and particularly relates to the application of a zinc phthalocyanine complex as ink in micro-contact printing. Background technique [0002] Microcontact printing, as a soft lithography technique for material surface patterning, has developed rapidly in the past two decades. Compared with other printing techniques, microcontact printing has many advantages, such as simple operation, low cost, and strong adaptability to substrate surface roughness, etc. Recently, microcontact printing has been used to produce metal patterns on the surface of materials, but currently there are few inks to choose from, and patterns often suffer from expansion and distortion. Therefore, it is necessary to research and develop new, stable inks that can overcome problems such as pattern swelling and distortion. [0003] As a synthetic compound, phthalocyanine was studied by researchers as early as 1907. T...
