Currently, smart and functional textiles have attracted increasing attention for the research on their application in various fields. In this paper, perfluorooctyltriethoxysilane (FAS13)-loaded silica nanocapsules taken as the Pickering emulsifier was applied to stabilize O/W emulsion for obtaining pH-responsive dual-compartmental microcapsules which show a strawberry-like structure with jasmine essence as the core and pH-responsive polymers and silica nanocapsules as the shell. These microcapsules could endow it with multifunctions by functionalizing the fabric, while the preparation and functionalization process is effortless and environmental friendly. Not only does the treated fabric demonstrate the self-healing superhydrophobicity and ultraviolet (UV) resistance because of the hydrophobic FAS13 getting loaded into silica nanocapsules and the surface modification of UV absorbent, it is also capable of the pH control jasmine essence-releasing performance, which allows over 40% of the fragrance to be preserved for three months through the controlled release of jasmine essence from the microcapsules.
目前，智能功能性纺织品在各个领域的应用研究越来越受到关注。本文以负载全氟辛基三乙氧基硅烷（FAS13）的二氧化硅纳米胶囊作为Pickering乳化剂，用于稳定水包油乳液，以获得pH响应型双室微胶囊，其呈现出以茉莉香精为核心、pH响应型聚合物和二氧化硅纳米胶囊为壳的草莓状结构。这些微胶囊通过对织物进行功能化赋予其多种功能，同时制备和功能化过程简便且环保友好。经处理的织物不仅由于疏水性的FAS13负载到二氧化硅纳米胶囊中以及紫外线吸收剂的表面改性而表现出自愈超疏水性和抗紫外线（UV）性能，还具备pH控制茉莉香精释放性能，通过微胶囊中茉莉香精的控释，可使超过40%的香味在三个月内得以保留。
