The synthesis of multifunctional microcapsules using natural polymers has contributed to a broad range of practical applications on fabric coatings. This paper presents a facile and environment-friendly approach for waterborne multifunctional fabric coatings by using cellulose/silica hybrid microcapsules. In this method, lavender fragrance oil-loaded cellulose/silica hybrid microcapsules were one-step synthesized via emulsion solvent diffusion. This microcapsule is core-shell structure with UV absorbers and methacrylic acid grafted silica in the shell and then added into the waterborne polysiloxane resins to form multifunctional fabric coatings. The as-obtained fabric coatings not only exhibited controlled lavender fragrance oil-releasing performance, and it can keep above 30 % fragrance after ninety days due to the slow releasing of lavender fragrance oil in the capsules, but also showed excellent UV resistant property with 159 UPF value.

乙基纤维素/二氧化硅杂化微胶囊具有缓慢释放的香气和抗紫外线特性的多功能织物涂料。

使用天然聚合物合成多功能微囊已在织物涂层上的广泛实际应用中做出了贡献。本文提出了一种使用纤维素/二氧化硅杂化微胶囊的水性多功能织物涂料的简便且环境友好的方法。在该方法中，通过乳液溶剂扩散一步合成了薰衣草香料油负载的纤维素/二氧化硅杂化微胶囊。该微胶囊是核-壳结构，壳中具有紫外线吸收剂和甲基丙烯酸接枝的二氧化硅，然后添加到水性聚硅氧烷树脂中以形成多功能织物涂层。如此获得的织物涂料不仅表现出受控的薰衣草香精油释放性能，
