Abstract

Preparation of organo-silica nanoparticles dispersing in an isoparaffin Isopar L as a dispersion medium was explored aiming at use of the particles for microencapsulated electrophoretic displays. The particles were prepared by a procedure based on the Stöber method using a mixture of both TEOS and various organotrialkoxysilanes as silica sources. The particles obtained using octadecyltriethoxysilane or 3,3,3-trifluoropropyltrimethoxysilane were readily transferred by extraction in the Isopar L phase and the dispersions were successfully encapsulated in microcapsules.
