Problems solved by technology

Most of the existing substrates have defects such as complicated technology, expensive experimental equipment and raw materials; easy to damage, difficult to store and carry, etc.
[0006] Due to the uncontrollability of the processing of the randomly distributed particle film, it is not conducive to the commercial mass production of the substrate

Embodiment 1

[0036] A preparation method of a flexible Raman-enhanced adhesive tape, comprising the steps:

[0037] 1) PET film pretreatment: The PET film was washed with an aqueous solution of teepol detergent with a mass concentration of 0.1% at 60 °C for 30 minutes, then washed with deionized water for 10 minutes, and then washed with ethyl acetate at 60 °C for 30 minutes, and placed in a 60 °C oven Dry to constant weight in medium to obtain a clean PET film (see figure 1 );

[0038] 2) Amination: Immerse the clean PET film in an amine solution with a temperature of 85 °C for 2 h, take it out, wash with methanol for 90 min, and dry at 60 °C for 30 min to obtain an aminated PET film (see figure 2 ), for subsequent use; the amine solution is mixed with ethylenediamine and dimethyl sulfoxide in a molar ratio of 1:1;

[0039] 3) Adsorbing silver glue: Immerse the aminated PET film obtained in step 2) into a silver glue solution (the silver glue solution is prepared by the following steps...

Embodiment 2

[0042] The difference from Example 1 is that the amine solution is triethylenetetramine. The product obtained is denoted as A2 (see Figure 5 ).

Embodiment 3

[0044] The difference from Example 1 is that step 3) selects 0.02mol / L silver nitrate standard solution. The product obtained is denoted as A3 (see Image 6 ).

Abstract

The invention relates to a preparation method of a flexible Raman reinforced adhesive tape, which comprises the following steps: 1) Amination: immerse a clean PET film in an amine solution at a temperature of 80-90°C for 2-6 hours, take it out, wash it, and dry it , to obtain an aminated PET film for later use; 2) Adsorption of silver colloid: immerse the aminated PET film obtained in step 1) into the silver colloid solution, and let it stand for 24-48 hours to obtain the product. The flexible Raman-enhanced adhesive tape of the present invention has excellent Raman-enhanced effect, and also has the advantages of low cost, simple manufacture, easy transportation and storage, high strength and good toughness, and the like.

Description

technical field [0001] The invention belongs to the technical field of adhesive tape preparation, and in particular relates to a flexible Raman reinforced adhesive tape and a preparation method thereof. Background technique [0002] As a fast and efficient detection method, spectroscopic technology has been widely used in the rapid identification and screening of pollutants. Surface-enhanced Raman spectroscopy (SERS), as one of the spectral detection technologies, has the advantages of high sensitivity, less moisture interference, and can provide Near-field enhancement and suitability for studying interface effects, etc., have significant advantages in trace non-destructive rapid detection. At present, surface-enhanced Raman spectroscopy has been used in the rapid detection of organic pollutants such as catalysis, spectroelectrochemistry, sensing, drug residues, antibiotics, and heavy metal pollutants. In the research of surface-enhanced Raman spectroscopy, the preparation ...
