Notes:
Preparation of monodispersed inorganic-organic hybrid particles has become one of themost attractive research topics in recent years. In this study, phenylsilsesquioxane (PhSiO3/2) particleswere synthesized from phenyltriethoxysilane (PhSi(OEt)3), ethanol (EtOH), hydrochloric acid forhydrolysis and ammonia water for polycondensation by the sol-gel method. Spherical PhSiO3/2particles were obtainable by varying the mole ratios of EtOH, H2O, HCl and NH3, to PhSi(OEt)3. Theparticle size was changed from 0.1 to 5.0 .m with the mole ratio. Under the optimum conditions,monodispersed particles with 1.50 .m in diameter and 0.05 of normalized standard deviation weresuccessfully prepared
