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.

聚丙烯酸酯复合材料的制备,表征及其在有机硅改性ZnO基超疏水涂料中的应用

通过端粒化合成了一种含双键和氢键的有机硅。为了将ZnO分散并掺入聚合物基质中,ZnO用有机硅改性。最后,使用改性的ZnO和有机硅制备ZnO /聚丙烯酸酯和有机硅/聚丙烯酸酯复合材料。本研究报告了通过原位乳液聚合合成和表征ZnO /聚丙烯酸酯和有机硅/聚丙烯酸酯纳米复合材料。系统研究了ZnO和有机硅对复合材料的形貌结构和热性能的影响。使用FTIR,XRD,SEM,TEM,TGA,粒度分析,UV和WCA对复合材料进行表征。可以看出,随着ZnO和硅酮的加入,复合材料的热降解温度显着提高。SEM分析表明,薄膜与表面改性的ZnO纳米粒子均匀分布。然后,使用改性的ZnO和硅氧烷/聚丙烯酸酯乳液制备改性的ZnO /聚丙烯酸酯超疏水复合涂层。该涂层具有出色的自清洁和油水分离特性。
