- Abstract
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. The ORMOSIL lavender fragrance nanospheres were arranged uniformly and spherically with mean diameter sizes 220.5 nm. 96.36% of encapsulation efficiency was achieved in optimal conditions.
