Embodiment 1

[0028] 1) Substrate surface treatment: Soak polymethyl methacrylate in 45% isopropanol aqueous solution for 30 minutes, wherein the mass percentage of isopropanol solution and polymethyl methacrylate is 1:1. Then put it in 2mol / L sulfuric acid solution, and soak it for 15 minutes at a temperature of 55°C, then wash it with water, and carry out vacuum drying at a temperature of 60°C, and introduce carboxyl groups on the surface of the polymer substrate to obtain carboxylated polymer. Methyl methacrylate base;

[0029] 2) Prepare a composite solution of β-cyclodextrin and tert-butoxyacetyl ruthenium compound: dissolve the β-cyclodextrin in water to obtain an aqueous solution of β-cyclodextrin with a concentration of 3 g / L, and in every liter of β-cyclodextrin Add 0.8 g of tert-butoxyacetyl ruthenium compound to the aqueous solution, and then use an ultrasonic instrument to adjust the frequency to 20 kHz for 30 minutes to obtain a uniformly dispersed composite solution of β-cyclo...

Embodiment 2

[0034] 1) Substrate surface treatment: soak polymethyl methacrylate with 55% isopropanol aqueous solution for 60 minutes, wherein the mass percentage of isopropanol solution and polymethyl methacrylate is 1 ∶ 5. After taking it out, place it in a 3mol / L sulfuric acid solution, soak it for 20 minutes at a temperature of 65°C, then wash it with water, and carry out vacuum drying at a temperature of 65°C to introduce carboxyl groups on the surface of the polymer substrate to obtain Carboxylated polymethyl methacrylate base;

[0035]2) Prepare a composite solution of β-cyclodextrin and tert-butoxyacetyl ruthenium compound: dissolve β-cyclodextrin in water to obtain an aqueous solution of β-cyclodextrin with a concentration of 6 g / L. Add 0.8 g of tert-butoxyacetyl ruthenium compound to the aqueous solution, and then use an ultrasonic instrument to adjust the frequency to 20 kHz for 60 minutes to obtain a uniformly dispersed composite solution of β-cyclodextrin and tert-butoxyacetyl...

Embodiment 3

[0040] 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 substrates obtained in Example 1 and Example 2 and the polymethyl methacrylate 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 polymethyl methacrylate substrate before carboxylation, and the cells cultured in complete culture medium as the experimental group and the control group. Contain cells and culture medium as a blank control, move the culture plate to 37°C, 5% CO 2 Incubator cultivation. After 24 hours, discard the culture medium, wash the pl...

Abstract

The invention relates to a tert butyl acetyl ruthenium compound and further provides application of a beta-cyclodextrin and tert butyl acetyl ruthenium compound composite solution in the microcontact printing technology. Beta-cyclodextrin is dissolved in water to obtain a beta-cyclodextrin water solution with the concentration of 3-6 g / L, 0.8g of tert butyl acetyl ruthenium compound is added to each liter of beta-cyclodextrin water solution, then the frequency is adjusted to 20 kHz ultrasound for 30-60 min by an ultrasonic apparatus, and a PDMS seal is soaked with an obtained homodisperse beta-cyclodextrin and tert butyl acetyl ruthenium compound composite solution and a carboxylation substrate is covered with the seal for electroless plating. According to the beta-cyclodextrin and tert butyl acetyl ruthenium compound and the application of the compound in the microcontact printing technology, a new thought is provided for microcontact printing ink in preparing metal patterns in the surface of a polymer substrate frequently used in the electron industry and the microcontact printing industry.

Description

technical field [0001] The invention belongs to the field of modern electronic technology, and particularly relates to the application of a beta-cyclodextrin and tert-butoxyacetyl ruthenium compound 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)...
