Example Embodiment
[0037] Example 1
[0038] Take the pre-prepared methanol / distilled water solution (volume ratio 1:1), add nitrogen to it for 10 minutes, add 4g methacrylic acid 3-sulfonate propyl potassium salt, 0.2g N-(3,4- Dihydroxyphenyl) ethyl-methacrylamide, 0.1 g of 2,2'-bipyridine, 0.05 g of benzyl bromide, reacted for 4 hours at room temperature under nitrogen protection, and then precipitated the copolymer with methanol.
[0039] The copolymer was prepared into an aqueous solution with a concentration of 0.01 g / mL, and the titanium or titanium alloy was immersed in the solution for 25 hours, and washed with water and methanol several times to dry.
Example Embodiment
[0040] Example 2
[0041] Take the pre-prepared methanol / distilled water solution (volume ratio 1:1), add nitrogen to it for 15 minutes, add 4.5g methacrylic acid 3-sulfopropyl potassium salt, 0.2g N-(3,4 -Dihydroxyphenyl)ethyl-methacrylamide, 0.1g 2,2'-bipyridine, 0.05g benzyl bromide, reacted for 4h at room temperature under nitrogen protection, and then precipitated the copolymer with methanol.
[0042] The copolymer was prepared into an aqueous solution with a concentration of 0.05 g / mL, and the titanium or titanium alloy was soaked in the solution for 25 hours, and washed with water and methanol several times to dry.
Example Embodiment
[0043] Example 3
[0044] Take the pre-prepared methanol / distilled water solution (volume ratio 1:1), add nitrogen to it for 20 minutes, add 5g methacrylic acid 3-sulfopropyl potassium salt, 0.3g N-(3,4- Dihydroxyphenyl) ethyl-methacrylamide, 0.2g 2,2'-bipyridine, 0.06g benzyl bromide, reacted at room temperature for 5 hours under nitrogen protection, and then precipitated the copolymer with methanol.
