Examples
Embodiment 1
[0026] (1) Alkaline buffer solution: Tris-0.1g; H 2 O-80ml; hydrochloric acid solution-0.1mol / L; pH=7.5;
[0027] (2) Dopamine modified solution: 2mg / ml
[0028] (3) Sample to be modified: 304 stainless steel
[0029] Such as image 3 and Figure 4 It can be seen that the surface of the sample coated by ultrasonic coating for 2 hours is more hydrophilic than the sample coated by static coating for 24 hours, and the surface of stainless steel coated by ultrasonic is more glossy, and the coating is denser and smoother.
Embodiment 2
[0031] (1) Alkaline buffer solution: Tris-0.2g; H 2 O-100ml; hydrochloric acid solution-1mol / L; pH=9.5;
[0032] (2) Dopamine modified solution: 6mg / ml
[0033] (3) Sample to be modified: glass slide
[0034] Such as Figure 5 and Figure 6 It can be seen that the hydrophilicity of the surface of the sample coated by ultrasonic coating for 2 hours and static coating for 24 hours is similar, and the coating of the ultrasonic coated glass slide is denser, smoother and more uniform.
Embodiment 3
[0036] (1) Alkaline buffer solution: Tris-0.121g; H 2 O-90ml; hydrochloric acid solution-0.2mol / L; pH=8.5;
[0037] (2) Dopamine modified solution: 3mg / ml
[0038] (3) Sample to be modified: plastic PET
[0039] Such as Figure 7 and Figure 8 It can be seen that the hydrophilicity of the surface of the sample coated by ultrasonic coating for 2 hours is better than that of the sample coated by static coating for 24 hours, and the coating of the ultrasonic coated glass slide is denser, smoother and more uniform.
