本文采用调聚法合成了一种含双键和氢键的有机硅。为了将ZnO分散并引入到聚合物基体中，用有机硅对ZnO进行改性。最后，以改性ZnO和有机硅为原料，制备了ZnO/聚丙烯酸酯和有机硅/聚丙烯酸酯复合材料。采用原位乳液聚合法制备了ZnO/聚丙烯酸酯和有机硅/聚丙烯酸酯纳米复合材料，并对其进行了表征。系统研究了ZnO和有机硅对复合材料形态结构和热性能的影响。采用FTIR、XRD、SEM、TEM、TGA、粒度分析、UV、WCA等手段对复合材料进行了表征。结果表明，ZnO和有机硅的加入显著提高了复合材料的热降解温度。SEM分析表明，薄膜表面均匀分布着表面修饰的ZnO纳米粒子。然后，将改性ZnO与有机硅/聚丙烯酸酯乳液复合，制备了改性ZnO/聚丙烯酸酯超疏水复合涂层。该涂料具有优良的自清洁和油水分离性能。
In this paper, a kind of silicone containing double bond and hydrogen bond has been synthesized via telomerization. In order to disperse and incorporate ZnO into the polymer matrix, ZnO was modified with silicone. Finally, ZnO/polyacrylate and silicone/polyacrylate composites were prepared using modified ZnO and silicone. The present study reports synthesis and characterization of ZnO/polyacrylate and silicone/polyacrylate nanocomposites by in situ emulsion polymerization. The effects of ZnO and silicone on the morphological structure and thermal properties of composites were systematically studied. The composites were characterized using FTIR, XRD, SEM, TEM, TGA, particle size analysis, UV, and WCA. It could be seen that the thermal degradation temperature of the composites increased significantly with the addition of ZnO and silicone. SEM analysis showed that the films were evenly distributed with the surface-modified ZnO nanoparticles. Then, the modified ZnO/polyacrylate superhydrophobic composite coating was prepared using modified ZnO and silicone/polyacrylate emulsion. The coating has excellent self-cleaning and oil-water separation properties.
