Lavender fragrance (LF) was encapsulated successfully in ORMOSIL (organically modified silica) via the sol‐gel approach. Silane precursor‐ethylsilicate (TEOS) was modified with methyltrimethoxysilane (MTMS) to enhance the mechanical strength and compatibility of the wall material. Hexadecyl trimethyl ammonium bromide (CTAB) was added as surfactant and polymer for the formation of nanospheres. An encapsulation efficiency of 96.36% was achieved under optimal conditions (water/ethanol ratio of 2 : 1, with pH 9.5, and with a surfactant concentration of 25 mM). Moreover, a scanning electron microscope (SEM) image of the LF nanospheres showed that the nanospheres were spherical with good dispersibility. The Fourier transform infrared spectroscopy (FTIR) analysis indicated that LF was successfully encapsulated in organically modified silica. The result of thermogravimetric (TG) analysis showed that the nanospheres had excellent thermal stability. Furthermore, the SEM image of aromatic wallpaper indicated a successful application of the LF nanospheres in wallpaper.

薰衣草香气溶胶凝胶封装在ORMOSIL纳米球中

薰衣草香精（LF）通过溶胶-凝胶法成功地封装在ORMOSIL（有机改性的二氧化硅）中。硅烷前体-硅酸乙酯（TEOS）用甲基三甲氧基硅烷（MTMS）改性，以增强墙体材料的机械强度和相容性。加入十六烷基三甲基溴化铵（CTAB）作为表面活性剂和聚合物，以形成纳米球。在最佳条件下（水/乙醇比为2：1，pH值为9.5，表面活性剂浓度为25 mM），封装效率达到了96.36％。此外，LF纳米球的扫描电子显微镜（SEM）图像显示该纳米球是球形的，具有良好的分散性。傅立叶变换红外光谱（FTIR）分析表明，LF已成功封装在有机改性的二氧化硅中。热重分析（TG）的结果表明，纳米球具有优异的热稳定性。此外，芳烃墙纸的SEM图像表明LF纳米球在墙纸中的成功应用。
