Embodiment 1

[0026] N-(3,4-dihydroxyphenyl) ethyl-methacrylamide copolymer, the structural formula of the copolymer is:

[0027]

[0028] N-(3,4-dihydroxyphenyl) ethyl-methacrylamide copolymer is prepared by the following method: ① In parts by weight, weigh 3 parts of 1-allyl-4-(tri Fluoromethyl)benzene, 0.2 parts of N-(3,4-dihydroxyphenyl)ethyl-methacrylamide, 0.03 parts of cuprous chloride, 0.4 parts of 2,2′-bipyridyl, 0.03 parts of benzyl bromide ; ② take the toluene that has been dried in advance, and pass it into argon for 15 minutes; add the materials prepared in step ① into the toluene, and stir and react for 6 hours under the protection of argon at a temperature of 50 ° C; the reaction equation is as Eq .1 shown. ③ Evaporate the solution after the reaction in step ②, and then wash it with methanol and acetone for 4 times to remove the solvent attached to the surface of the precipitate to obtain the product. Each part by weight is 10 g.

Abstract

The invention discloses an N-(3,4-dihydroxyphenyl)ethyl-methyl acrylamide copolymer and a preparation method thereof. In the invention, with dopamine and a fluorine-containing compound as raw materials, the dopamine is modified with the fluorine-containing compound through copolymerization to prepare the copolymer containing a fluorine-containing compound side chain and a pyrocatechol anchoring group side chain. The copolymer, on one hand, has the pyrocatechol anchoring group of the dopamine, so that excellent adhesion performance is achieved, and on the other hand, has the fluorine-containing functional group, so that the copolymer has weather resistance, corrosion resistance and hydrophobicity and lipophobicity, thereby greatly improving the protective performance of a functional protective coating. The invention also discloses a functional protective surface material having excellent adhesion performance, which is prepared by self-assembling the N-(3,4-dihydroxyphenyl)ethyl-methyl acrylamide copolymer onto a surface of a material in a soaking manner. The material has excellent protective performance, super-hydrophobicity, anti-fouling performance and adhesion performance, is wide in substrate available range, and is toxic-free and zero-pollution.

Description

technical field [0001] The invention belongs to the field of materials, in particular to a functional protective surface material, in particular to a functional protective surface material with good adhesion performance and a preparation method thereof. Background technique [0002] With the rapid development of the marine economy and the acceleration of the use of marine space, marine structural engineering such as breakwaters, piers, sea airports, subsea tunnels and sea-crossing bridges has become more and more widely used. At the same time, due to long-term immersion in seawater, erosion, and the impact of wind waves and tides, the corrosion of marine structural engineering has become increasingly prominent, seriously endangering the safety and durability of marine structural engineering. Therefore, more and more attention has been paid to the corrosion protection of marine structures. At present, the 100-year safe service requirement for marine structural engineering ne...
