    "protocol": "The self-designed silicone modified acrylic zwitterionic polymer is copolymerized by acrylic monomers as acrylic macromolecular skeleton, sulfonic acid quaternary ammonium salt as hydrophilic monomer, and the silane as a stabilization component.Synthesize 3-(bis(hydroxymethyl)amino)-2-hydroxypropyl methacrylate (D-GMA) by mixing diethanolamine (DEA) and glycidylmethacrylate (GMA) in a molar ratio of 1:1 in tetrahydrofuran solvent. Stir the mixture for 3 hours at 60°C under refluxing conditions until the solution is transparent. Wash the mixture repeatedly with 5-7 ml of dichloromethane and water to remove unreacted DEA and GMA, retaining the aqueous supernatant. Remove residual water from the aqueous supernatant fraction via rotary evaporation to obtain D-GMA with a yield of 30%.To synthesize the silicone modified acrylic resin hydrophilic polymer (SMA-H), five monomers including D-GMA, AMPS, HEMA, MMA, and BA were used. The synthesis involved two steps: First, 10 ml DMF was heated to 60°C in a 250 ml three-neck flask, and MMA, BA, and KH-570 were added in a molar ratio of 3:1:2. AIBN was added at approximately 0.3%. After reacting for 1 hour, a low molecular weight copolymer was obtained. Second, the low molecular weight copolymer was reacted with HEMA, AMPS, and D-GMA in a molar ratio of 3:1:3 at 60°C for 4 hours.1. Configure the silicone modified acrylic resin hydrophilic polymer (SMA-H), solvent, hydrolysis catalyst, and leveling agent to form a mixture. 2. Prepare the solvent by mixing iso-propyl alcohol (IPO) and ethylene glycol monomethylether (EE) in a volume ratio of 1:1. 3. Mix the silicone modified acrylic resin hydrophilic polymer and the solvent in a volume ratio of 2:3, stirring to obtain a diluted solution. 4. React the diluted solution with an acetic acid solution (pH=4, mass fraction 0.04%) and BYK-300 leveling agent (mass fraction 0.1%) at 40°C for 0.5 hours to obtain the silicone modified acrylic resin hydrophilic coating mixture. 5. Graft the hydrophilic polymer of SMA-H onto a pretreated PC board (5cm x 5cm). 6. Immerse the PC board into a solution containing PVB and ethanol (with PVB mass fraction between 0.05%-0.1%) for 3 minutes. 7. Dry the surface-treated PC board at 80°C for 10 minutes. 8. Deposit the silicone modified acrylic hydrophilic coating with approximately 20μm thickness onto the pretreated PC board using a bar applicator at a heat treatment temperature of 110°C for 2 hours."
