| 目的 制备一种新型绿色环保的耐海洋微生物附着涂层。 方法 通过聚硅氧烷(有机硅)改性丙烯酸树脂,合成以硅氧烷为侧链,丙烯酸树脂为主链的有机硅改性丙烯酸树脂。 利用聚多巴胺的粘附性和还原性,制备二氧化硅/ 聚多巴胺/ 纳米银(SiO2 / PD/ Ag)纳米复合材料。 以制备的有机硅改性丙烯酸树脂为成膜物,以载银纳米颗粒为杀菌剂,制备耐微生物附着环保涂层。 通过傅里叶红外光谱仪(FT-IR)和接触角检测仪(CA)分别对有机硅改性丙烯酸树脂的 Si—O 基团和接触角作表征,通过透射电子显微镜(TEM)表征 SiO2 / PD/ Ag 的制备过程,通过水解率和细菌附着等实验评价涂层的防污性能。 结果Si—O—Si 和 Si—O—C 的接入使得丙烯酸树脂改性后的接触角从 72°提高到 96°。 SiO2 / PD/ Ag 是一种特殊“核-壳-卫星冶结构的载银纳米颗粒,纳米银均匀分散在 SiO2 的表面。 涂层的水解性能良好,水解率为 1. 03 μm/ d,杀菌剂分散均匀。 结论 该涂层通过自抛光和低表面能双重物理抑菌作用和纳米银的杀菌作用,能有效抑制海洋微生物在试样表面的附着。 |

| Objective To prepare a novel green antifouling coating against marine microorganisms. Methods Acrylic resin was modified by polysiloxane (silicone), and silicone-modified acrylic resin with acrylic resin as the backbone and siloxane as the side chain was synthesized. Silica/ polydopamine/ silver (SiO2 / PD/ Ag) nanocomposites were prepared taking advantage of the adhesive and reductive properties of polydopamine. The green antifouling coating was prepared by taking the modified acrylic resin as the matrix material and mixing with silica / polydopamine / silver (SiO2 / PD / Ag) nanocomposites as bactericide. The Si—O group and contact angle of the silicone-modified acrylic resin were characterized by Fourier transform infrared spectrometer (FT-IR) and contact angle detector (CA),respectively, the preparation process of SiO2 / PD / Ag was characterized by transmission electron microscope (TEM), and the antifouling property of the coating was investigated by hydrolysis rate and bacterial adhesion. Results The introduction of Si—O—Si and Si—O—C increased the contact angle of the modified acrylic resin from 72° to 96°. SiO2 / PD / Ag is a special silver nanoparticle with " core-shell-satellite" structure, and the silver nanoparticles were evenly distributed on the surface of SiO2. The coating had a good hydrolysis performance, with a hydrolysis rate of 1. 03 μm/ d, and the bactericide was distributed evenly. Conclusion The coating had double physical antibacterial property through self-polishing and low surface energy, and the silver nanoparticles also had sterilizing property, and could therefore effectively inhibit the adhesion of marine microorganisms on the sample surface. |
