The aim of this work was to study the morphology and physical properties of siloxane–polyacrylate (SPA) dispersion and coating films. The SPA dispersion was synthesized by seeded emulsion polymerization using two different types of silane coupling agents, i.e., vinyltriethoxysilane (VTES) and 3-(trimethoxysilyl) propyl methacrylate (MPTMS), at 1–9% by weight. The effect of the type and content of silane coupling agent used in the SPA dispersion synthesis on the resulting morphology and physical properties of the obtained SPA dispersion and coating films were studied. The results revealed that SPA dispersion synthesized using VTES exhibited a smaller particle size and a higher stability than those using MPTMS. Furthermore, the hydrophobic surfaces and water repellence of the coating films using VTES in the emulsion were higher than those using MPTMS, due to the smoother surface morphology.

这项工作的目的是研究硅氧烷-聚丙烯酸酯（SPA）分散体和涂膜的形态和物理性能。通过使用两种不同类型的硅烷偶联剂（即乙烯基三乙氧基硅烷（VTES）和甲基丙烯酸3-（三甲氧基甲硅烷基）丙酯（MPTMS））以1-9％的重量通过种子乳液聚合合成SPA分散体。研究了SPA分散体合成中所用硅烷偶联剂的类型和含量对所得SPA分散体和涂膜的形态和物理性能的影响。结果表明，与使用MPTMS相比，使用VTES合成的SPA分散体具有更小的粒径和更高的稳定性。此外，
