Embodiment 1

[0029] 1) Substrate surface treatment: Soak polyethylene in 45% isopropanol aqueous solution for 30 minutes, wherein the mass percentage of isopropanol solution and polyethylene is 1:1, take it out and put it in 2mol / L sulfuric acid solution immersion at a temperature of 55°C for 15 minutes, then washed with water, and vacuum-dried at a temperature of 60°C to introduce carboxyl groups on the surface of the polymer substrate to obtain a carboxylated polyethylene substrate;

[0030] 2) Prepare the composite solution of γ-cyclodextrin and ruthenium complex: dissolve γ-cyclodextrin in water to obtain an aqueous solution of γ-cyclodextrin with a concentration of 3 g / L, and add 0.8 g ruthenium complex, and then use an ultrasonic instrument to adjust the frequency to 20kHz for 30 minutes to obtain a uniformly dispersed γ-cyclodextrin and ruthenium complex composite solution;

[0031] 3) Microcontact printing: Soak the PDMS stamp in the composite solution of γ-cyclodextrin and rutheni...

Embodiment 2

[0035] 1) Substrate surface treatment: Soak polyethylene in 55% isopropanol aqueous solution for 60 minutes, wherein the mass percentage of isopropanol solution and polyethylene is 1:5, take it out and put it in 3mol / L sulfuric acid solution , and soaked at a temperature of 65°C for 20 minutes, then washed with water, and vacuum-dried at a temperature of 65°C to introduce carboxyl groups on the surface of the polymer substrate to obtain a carboxylated polyethylene substrate;

[0036] 2) Preparation of γ-cyclodextrin and ruthenium complex solution: dissolve γ-cyclodextrin in water to obtain an aqueous solution of γ-cyclodextrin with a concentration of 6 g / L, and add 0.8 g ruthenium complex, and then use an ultrasonic instrument to adjust the frequency to 20kHz for 60 minutes to obtain a uniformly dispersed γ-cyclodextrin and ruthenium complex composite solution;

[0037] 3) Microcontact printing: Soak the PDMS stamp in the composite solution of γ-cyclodextrin and ruthenium comp...

Embodiment 3

[0041] Human normal epidermal cells HaCaT were cultured in Dulbecco's Modified Eagle's Medium (DMEM) medium (containing 10% newborn bovine serum) at 37°C and 5% CO 2 Cultivate under conditions, and change the culture medium once every 1-2 days. When the cells grow to the logarithmic phase, the metal pattern substrate obtained in Example 1 and Example 2 and the polyethylene substrate before carboxylation are added for treatment. Place the cells in a 96-well plate with 0.25% trypsin at 37°C, 5% CO 2 Incubator cultivation. After 2 to 4 hours, each culture plate was added with the metal pattern substrate obtained in Example 1 and Example 2, the polyethylene substrate before carboxylation and the cells cultured in complete culture medium as the experimental group and the control group, without cells and cultured solution as a blank control, the culture plate was moved to 37 ℃, 5% CO 2 Incubator cultivation. After 24 hours, discard the culture medium, wash the plate twice with p...

Abstract

The invention relates to a ruthenium complex, and also provides an application of a compound solution of the ruthenium complex and gamma-cyclodextrin in a micro-contact printing technology. A gamma-cyclodextrin aqueous solution the concentration of which is 3-6g / L is obtained by dissolving gamma-cyclodextrin with water, 0.8g of the ruthenium complex is added into every liter of the gamma-cyclodextrin aqueous solution, and then the frequency is adjusted to be 20kHz by using an ultrasonic instrument to perform ultrasounding for 30-60 minutes so as to obtain a uniformly dispersed compound solution of gamma-cyclodextrin and ruthenium complex for soaking a PDMS (polydimethylsiloxane) stamp, and the stamp is stamped on a carboxylic substrate to perform chemical plating. The invention provides a new thought for preparation of metal patterns on the surface of a polymer substrate which is commonly used in the electronics industry by using a micro-contact printing ink, and for the micro-contact printing industry.

Description

technical field [0001] The invention belongs to the field of modern electronic technology, and particularly relates to the application of a gamma-cyclodextrin and ruthenium complex as a composite green ink in micro-contact printing technology. Background technique [0002] Surface micro-structuring technology is gradually showing important application value, especially micro-contact printing technology, which can be micro-patterned on a small scale, which is of great significance in many fields, especially in the field of modern electronic technology. At present, there are few microcontact printing inks to choose from, and the materials that can be printed on the surface are limited. A large number of materials cannot be prepared with surface patterns by microcontact printing. Therefore, it is of great significance to develop new and stable inks. [0003] The applicant disclosed eight (octyloxy)-phthalocyanine zinc in the authorized patent (CN 102516841 B) as ink in polyeth...
