Sol–Gel Microcapsulation in Silica-Based Particles: A Comparative Study

摘要

We compare the two main sol-gel/emulsion methods to prepare silica-based microparticles doped with actives. Moreover, we analyze the morphpology of the resulting particles varying also the nature of the organosilane, and the pH of the sol-gel process. Benzoyl peroxide was used as molecular dopant.
