Embodiment 1
[0031] Embodiment 1 A kind of invisible ink and preparation method thereof
[0032] refer to figure 1 As shown in the preparation flow chart of the invisible ink, the composition and preparation of the invisible ink include the following steps:
[0033] Step S1: The effect of preparing PS microspheres from the microemulsion. Dissolve PS particles in toluene solution to prepare PS toluene solution with a mass fraction of 1%, add single fluorescent dyes coumarin 6 and anthracene respectively, and prepare PS toluene@coumarin 6 and PS with dye mass concentration of 0.1% Toluene@anthracene fluorescent solution;
[0034] Step S2: Mix 2mL of 1wt% PS toluene@coumarin 6 solution with 14mL of SDS solution with a concentration of 5mg / mL, add magnets, and stir for 1 hour on a magnetic rotary machine at a speed of 300r / min to obtain ultrasonic emulsification system;
[0035] Step S3: circulate the solution obtained in step S2 on the ultrasonic cell breaker with a power of 10% and a wor...

Embodiment 3
[0041] Embodiment 3 A kind of invisible ink and preparation method thereof
[0042] refer to figure 1 As shown in the preparation flow chart of the invisible ink, the composition and preparation of the invisible ink include the following steps:
[0043] Step S1: The effect of preparing PS microspheres from the microemulsion. Dissolve PS particles in toluene solution to prepare a PS toluene solution with a mass fraction of 1%, add fluorescent dyes coumarin 6 and anthracene (mass ratio: 5%:95%), and prepare PS with a mass concentration of 0.1%. Toluene@coumarin 6@anthracene fluorescent solution;
[0044] Step S2: Take 2mL of 1wt% PS toluene@anthracene fluorescence solution and mix 14mL of SDS solution with a concentration of 5mg / mL, add a magnet, and stir for 1 hour on a magnetic machine at a speed of 300r / min to obtain a system to be phacoemulsified ;
[0045] Step S3: circulate the solution obtained in step S2 on the ultrasonic cell breaker with a power of 10% and a workin...
