- Much attention has been paid to the surface modification of inorganic particles to have a hydrophobic
property on its surface that can be applicable to a polymer composite. We have been evaluating
the silanepolyols as a modifier instead of alkoxysilane, which is widely used. In this study,
spherical silica (200±30 nm) was prepared1 and modified with a silanepolyol2, PhSi(OH)3, in a
wide range from 0.1 to 10 wt % based on the silica used. Characterizations of the modified particles
were carried out using various analytical tools (SEM, TEM, DLS, etc.). Herein, recent results for
the surface modification approach to silica and several inorganic particles (TiO2, SnO2, ZnO) including
their detailed analytical results will be discussed.
