Abstract
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 (230±30 nm) was prepared and modified with a silanepolyol, 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.
