[0002] Traditional marine antifouling coating generally relies on toxic substances such as organotin and copper compounds, which causes serious damage to the marine ecological environment. Although acrylic resin-based coating has lower toxicity, it has the problem of insufficient anti-bioadhesion. Polyoxazoline material is concerned due to its excellent hydrophilicity, protein adsorption resistance and biocompatibility. However, there is no report in the prior art that polyoxazoline segments are introduced into the acrylic resin skeleton by chemical bonding and used to prepare marine antifouling materials with environmental protection, long-term antifouling and structural stability. SUMMARY

[0007] Further, the synthesis method of the above-mentioned oxazoline-based acrylic ester polymer antifouling material comprises the following steps:

Under the protection of inert gas, oxazoline monomer is subjected to cationic ring-opening polymerization to generate active polyoxazoline chain, then methyl methacrylate anion is used to terminate the reaction, the reaction is cooled to room temperature after the reaction is completed, potassium carbonate is added and stirred for neutralization, then centrifugal separation is carried out, the filtrate is filtered through a microporous filter membrane, the solvent is removed by evaporation under reduced pressure to obtain a solid. The solid is dissolved and washed with methanol, and then precipitated and separated out in ethyl ether to obtain a precipitate. The precipitate is vacuum dried to obtain oligomeric oxazoline methyl methacrylate monomer. The chemical reaction equation is as follows:
[0009] .
[0010] S2. Mix toluene and ethanol to obtain a solvent, and heat the solvent to 78-82℃. Under an inert gas atmosphere, mix methyl methacrylate, ethyl acrylate, methacrylic acid, oligomeric 2-oxazoline methacrylate monomer, free radical initiator I, and chain transfer agent evenly to obtain a mixture. Add the mixture dropwise to the solvent for 4-6 hours, and continue the reaction for another 2-4 hours. Then add free radical initiator II dropwise to the solvent for 1-2 hours, and continue the reaction for another 3-4 hours to obtain a reaction solution. After the reaction is complete, cool the reaction solution to room temperature, and slowly add the reaction solution dropwise to n-hexane while stirring to precipitate the polymer. Repeat the precipitation / dissolution process at least 3 times, and then vacuum dry to obtain an oxazoline acrylate polymer antifouling material. The chemical reaction equation is as follows:
[0011] .
[0012] Furthermore, the inert gas in S1 is nitrogen or argon, and the cationic ring-opening polymerization uses methyl trifluoromethanesulfonate as the initiator and acetonitrile as the solvent. The molar ratio of the initiator to the oxazoline monomer is 1:5-20.
[0013] Furthermore, in S1, the ring-opening polymerization reaction temperature is 85-95℃, the reaction time is 45-90 min, the stirring speed for stirring and neutralization is 200-400 rpm, the stirring and neutralization time is 20-30 h, the centrifugation speed is 3000-8000 rpm, the centrifugation time is 5-10 min, the microporous filter membrane pore size is 15-25 µm, the vacuum drying vacuum degree is -0.08~-0.10 MPa, the drying temperature is 30-40℃, and the drying time is 10-15 h.
[0014] Furthermore, in S1, the reaction is terminated by adding methacrylate and triethylamine to terminate the reaction. The termination temperature is 60-80℃, and the reaction time is 12-24h. The molar ratio of methacrylate, triethylamine and oxazoline monomer is 1:(0.9-1.1):(2-3).
[0015] Furthermore, in S2, toluene and ethanol are mixed at a volume ratio of 1:9-11, the inert gas is nitrogen or argon, the free radical initiator I in S2 is azobisisobutyronitrile, and the chain transfer agent is 2-cyano-2-propylbenzodisulfide.
[0016] Furthermore, the molar ratio of the total molar number of oligomeric 2-oxazoline methacrylate monomers to 2-cyano-2-propylbenzodisulfide is 60-300:1.
[0017] Furthermore, in S2, the mass ratio of methyl methacrylate, ethyl acrylate, methacrylic acid, free radical initiator I, and chain transfer agent is (180-220):(180-220):(40-50):(3.5-4.5):(4-6), and the molar ratio of free radical initiator II to free radical initiator I is 0.5-0.8:1. Free radical initiator II is a toluene / ethanol solution of benzoyl peroxide or tert-butyl peroxide (2-ethylhexanoate).
[0018] Furthermore, in the toluene / ethanol solution, the volume ratio of toluene to ethanol is 9-11:1; when the free radical initiator II is a toluene / ethanol solution of benzoyl peroxide, the volume ratio of benzoyl peroxide to toluene / ethanol solution is 1:23-27; when the free radical initiator II is a toluene / ethanol solution of tert-butyl peroxide (2-ethylhexanoate), the volume ratio of tert-butyl peroxide (2-ethylhexanoate) to toluene / ethanol solution is 1:23-27.
[0019] Furthermore, the reaction temperature in S2 is controlled at 75-85℃, the vacuum drying vacuum degree is -0.08~-0.10MPa, the drying temperature is 40-50℃, and the drying time is 4-8h.
[0020] Compared with the prior art, the beneficial effects of the present invention are:
[0021] 1. This invention polymerizes polyoxazoline segments onto the side chains of an acrylate copolymer via chemical bonding. These polyoxazoline segments possess strong hydrophilicity and rapid hydration capabilities. When the coating is immersed in seawater, these segments bind water molecules, forming a dense, dynamic "hydration layer" on the material surface. This hydration film constitutes an energy barrier, effectively repelling the approach and initial adhesion of biomolecules such as proteins and polysaccharides, thus preventing biofilm formation at its source. Furthermore, the polyoxazoline segments are connected to the polymer backbone through stable carbon-carbon bonds, ensuring the long-term and durable anti-adhesion function of the surface.
[0022] 2. The oxazoline acrylate polymer antifouling material of the present invention does not contain toxic substances such as heavy metals and organotin compounds. It achieves antifouling through a physical antifouling mechanism (forming a hydrophilic surface to inhibit the adhesion of marine organisms), which is environmentally friendly.

[0033] S1. Synthesis of oligomeric 2-methyl-2-oxazoline methacrylate monomer: Under nitrogen protection, 45 mL of acetonitrile, 1.45 g (8.85 mmol) of methyl trifluoromethanesulfonate, and 15.06 g (177.0 mmol) of 2-methyl-2-oxazoline were added sequentially to a dry reaction flask, and the mixture was stirred at room temperature until homogeneous. The reaction flask was then placed in a 90 °C oil bath and stirred for 45 min. Subsequently, the mixture was cooled to room temperature, and 1.988 g (23.1 mmol) of methacrylic acid and 2.34 g (23.1 mmol) of triethylamine were added. The reaction flask was then placed in a 70 °C oil bath and stirred for 14 h.

The mixture was centrifuged at 5000 rpm for 8 min, and the supernatant was filtered through a 20 µm filter membrane. The filtrate was distilled under reduced pressure to remove the solvent, yielding a solid. The obtained solid was dissolved and washed with 3 times its volume of methanol, and then slowly added dropwise to 10 times its volume of ice-cold anhydrous diethyl ether to precipitate. The precipitate was vacuum dried at -0.09 MPa and 35 °C for 12 h to obtain oligomeric 2-methyl-2-oxazoline methacrylate monomer.

The mixture was slowly added dropwise to the four-necked flask using a constant-pressure dropping funnel over 4 hours. After the addition was complete, the reaction was continued at 80 °C for another 4 hours. Subsequently, 1.12 mL of tert-butyl peroxide (2-ethylhexanoate) was dissolved in a mixed solvent of 23.07 mL toluene and 2.54 mL ethanol to obtain free radical initiator II. Free radical initiator II was slowly added dropwise to the reaction system over 1 hour. After the addition was complete, the reaction was continued at 80°C for 3 hours to obtain a reaction solution. After the reaction was completed, the reaction solution was cooled to room temperature. The reaction solution was then slowly added dropwise to 10 times its volume of n-hexane with stirring, causing a polymer precipitate to form. The precipitate was collected by filtration, dissolved in acetone, and the process of adding n-hexane to precipitate was repeated three times.

A control example (Example 1) was also included, where the sandblasted steel plates were not coated with the antifouling coating. Five plates from each example and comparative example were coated, and five plates from Control Example 1 were also prepared. The steel plates were immersed in a test tank containing natural seawater for 30 days. After immersion, the steel plates were removed and gently rinsed with phosphate buffer to remove any unattached microorganisms. Each rinsed steel plate was then wiped 20 times with a sterile cotton swab soaked in sterile saline solution. The swab head was then placed in a test tube containing 2mL of sterile saline solution, and the plate was vortexed at 2000rpm for 2 minutes to transfer the microorganisms from the swab into the liquid, yielding the eluent. Take 100 μL of elution buffer and 100 μL of ATP bioluminescent reagent and mix them in a detection tube.

[0053]
[0054] As shown in Table 1, the oxazoline-based acrylate polymer antifouling material prepared in this invention exhibits superior antibiofouling performance compared to commercially available acrylic resin-based marine antifouling coatings. This invention utilizes polyoxazoline segments as side links grafted onto the acrylate backbone. These polyoxazoline segments possess strong hydrophilicity and rapid hydration capabilities. When the coating is immersed in seawater, these segments bind water molecules, forming a dense, dynamic "hydration layer" on the material surface. This hydration film constitutes an energy barrier, effectively repelling the approach and initial adhesion of biomolecules such as proteins and polysaccharides, thus blocking biofilm formation at its source. Furthermore, the polyoxazoline segments are connected to the polymer backbone through stable carbon-carbon bonds, ensuring the long-term and durable antifouling function of the surface.
