中文摘要：

采用核壳乳液聚合的方法制备出具有疏水性能的氟硅丙乳液。探讨了膜疏水性能的影响因素，通过水接触角和多功能光电子能谱仪表征了有机氟在乳液成膜中的梯度分布功能，发现由于甲基丙烯酰氧基丙基三异丙氧基硅烷单体在涂膜固化过程中的马兰各尼效应以及与有机氟的相容性，对有机氟单体向表面迁移有促进作用，使膜疏水性能有较大提高。通过扫描电子显微镜观察到氟硅丙乳液膜表面呈现明显的由“蒲公英”状粒子排列交叉而成的枝状网络结构，与硅丙乳液膜有明显区别。

英文摘要：

A kind of acrylate emulsion with low surface energy modified with fluoroacrylate and siloxane was prepared by the core-shell emulsion polymerization. The impact factors of hydrophobic performance and cooperation effect of fluoride and silicide were discussed. The functionally gradient distribution of fluorine was analyzed by X-ray photoelectron spectroscopy. It is found that organic siloxane（C-1757） can provide a channel to be benefit for fluorine migrating to the film surface due to have a similar property of orientation on the surface and also serves as an anchor to the substrate by forming covalent bonds to increase adhesion. This result in the improvement of hydrophobicity of the film. The difference between the surface of films with or without fluorine was observed that dandelionshape particles arrange across to form branches-shape network on the surface of film with fluorine.
