Synthesis of Uniform Titania Microspheres

This study demonstrates the synthesis of uniform-sized titania microspheres for highly responsive optical materials by hydrolysis and condensation of titanium butoxide.
The preparation was performed using Tween20(polyoxyethylene (20) sobitan monolaurate, C58H114O26) as a stabilizer in acetone solvent at a room temperature.
Abstract
Introduction
Colloidal structures with a feature scale comparable to optical wavelength have been studied extensively because they have strong interaction with light.
The structural uniformity has been confirmed by unique scattering spectra from dilute dispersions of the fractionated clusters.
However, It is difficult to produce uniform titania microspheres with good dispersion stability from titanium alkoxides primarily because the precursors are too reactive to separate the seed formation and growth reaction stages.
The study introduced a stabilizing agent into the solgel reaction of a titanium precursor with reduced reactivity for the synthesis of highly stable monodisperse titania microspheres.
