摘要: 以甲基丙烯酸十二氟庚酯(FMA)、甲基丙烯酸聚二甲基硅氧烷基酯(SMA)、甲基丙烯酸甲酯、丙烯酸正丁酯、甲基丙烯酸正丁酯和丙烯酸乙酯为共聚单体,通过溶液聚合反应合成出侧链含有机氟、有机硅的丙烯酸树脂.通过核磁共振氢谱(1H-NMR)、核磁共振氟谱(19F-NMR)、红外光谱(FTIR)对聚合物的结构进行了表征.通过扫描电镜(SEM)、接触角测试和生物评价等方法,探讨了FMA、SMA含量对树脂涂膜性能的影响.结果表明氟硅改性的丙烯酸树脂比单独含氟或含硅改性的丙烯酸树脂具有更低的表面能,而且氟硅改性的丙烯酸树脂涂膜比商业化的聚硅氧烷涂膜具有更好的防污性能.

Abstract: The acrylic resins containing fluorine/silicone side chains were synthesized by solution copolymerization with 1H,1H,7H-dodecafluoroheptyl methacrylate (FMA),monomethacryloxyalkyl-terminated PDMS (SMA),methyl methacrylate (MMA),n-butyl acrylate (BA),n-butyl methacrylate (BMA) and ethyl acrylate (EA) as the comonomers.A solution of toluene and butyl acetate (weight ratio 1∶1) was initially charged to a 250 mL four-neck flask with a condenser,a nitrogen inlet and a mechanical stirrer.The mixture was then degassed for 15 min and immersed into an oil bath at 85℃ with a slow nitrogen purge.The mixture of FMA,SMA,MMA,BA,BMA,EA and 0.8% azobisisobutyronitrile (AIBN) ( based on the content of the comonomers)was slowly added dropwise over 2 h.0.4% AIBN was slowly added after the reaction was stirred over 1.5 h.The solution was heated to 110℃ and stirred for 2 h.The solid content of copolymer solution was 50%.The as-prepared copolymer was characterized by 1H-NMR,19F-NMR and FTIR.The effects of FMA and SMA content on the properties of polymer coatings were investigated by scanning electron microscopy (SEM) and contact angle analysis.The marine antifouling properties of the materials were evaluated by laboratory assays employing the fouling Sulfate-Reducing bacteria.The results showed the surface energy of fluorine modified acrylic resins and silicone modified acrylic resins were greater than 24 mJ/m2 and 29 mJ/m2,respectively.However,fluorine/silicone synergistically modified acrylic resins had lower surface energy (＜21 mJ/m2) and better anti-biofouling properties than fluorine or silicone-modified acrylic resins and a standard poly(dimethyl siloxane) (PDMS).
