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. Hydrophobic properties were examined by floating the modified particles on D.I. water and contact angle test by forming pelletized discs that the results presented the modified particles had a hydrophobic property even at a low amount of modifier (0.2 wt%). Herein, recent results for the surface modification approach to silica and the trend of morphological change at the case of pelletized discs will be discussed.
