摘要：

The method of preparation of microcapsules having liquid cores and hydrolyzed silica shells was demonstrated. Microcapsules were obtained by hydrolysis and condensation of silica sources contained in emulsion droplets. Tetraethyl orthosilicate {TEOS), (3 - Aminopropyl) triethoxysilane (APS) and Dimethyloctadecyl[3-(trimethoxysilyl) propyl] ammonium chloride (DTSAC1) were used as silica sources. The interfacial properties of chloroform-TEOS(APS, DTSAC1)/surfactant solution systems were investigated to determine the conditions favourable for emulsification. Emulsions were prepared using evaporation technique and stabilized, if it was necessary, by addition of TWEEN 80. Droplet size distribution, zeta potential and stability of emulsions were examined.
