Embodiment 1

[0024] The polytetrafluoroethylene substrate was soaked in 50% isopropanol aqueous solution for 30 minutes, then soaked in 3 mol / L sulfuric acid at 60°C for 15 minutes, then washed with water, and dried in vacuum at 60°C. Dissolve diphthalocyanine compound Eu in dichloromethane at a concentration of 1 g / L. Soak the PDMS stamp in the solution of diphthalocyanine and Eu in dichloromethane for 30s, take it out and put it in N 2 Dry in air flow for 30s. Cover the PDMS stamp coated with the solution of diphthalocyanine and Eu in dichloromethane on the carboxylated substrate, and press lightly for 10 seconds to transfer the PDMS stamp pattern to the surface of the substrate. Soak the printed substrate in 0.1g / LPdCl2 solution for 10s, take it out and place it in an electroless copper plating solution consisting of 5wt% copper sulfate, 7wt% sodium potassium tartrate, 6wt% sodium hydroxide, 32wt% formaldehyde and 50wt% distilled water Perform electroless plating for 3 minutes.

Abstract

The invention discloses an application of a double-layer sandwich-type Eu metal phthalocyanine complex in microcontact printing. The double-layer sandwich-type Eu metal phthalocyanine complex is bis(phthalocyanine) complexing Eu, and a metal pattern is obtained on a polytetrafluoroethylene substrate by virtue of a chemical plating method by taking a dichloromethane solution of the bis(phthalocyanine) complexing Eu as a printing agent of microcontact printing and transferring the pattern of a PDMS (Polydimethylsiloxane) seal to a carboxylation polytetrafluoroethylene substrate. According to the application, the fine metal patterns can be obtained by carrying out microcontact printing on the surface of the polytetrafluoroethylene substrate commonly used in an electron industry by taking the dichloromethane solution of the bis(phthalocyanine) complexing Eu as ink, so that the common phenomena of pattern expansion and distortion during the microcontact printing are effectively decreased, and the distinguishability is enhanced.

Description

technical field [0001] The invention belongs to the field of modern electronic technology, and particularly relates to the application of a double-layer sandwich type Eu metal phthalocyanine complex as a green environmental protection ink in micro-contact printing. Background technique [0002] Material surface patterning technology plays an important role in many fields including electronics technology and biomaterials. Traditional patterning technologies include photolithography, electron beam etching, X-ray etching, etc. These technologies usually rely on expensive large-scale equipment, and the processing environment and maintenance requirements are harsh, and the process is complex, which has great limitations . As a new material surface patterning technology, microcontact printing has the characteristics of fast, cheap and flexible operation methods compared with other printing technologies. At present, there are few microcontact printing inks to choose from, so micr...
