摘要：

Aqueous suspensions of hybrid particles have been prepared by means of a sol-gel process using the hydrolysis and condensation of tetraethoxysilane (TEOS) and methacryloxypropyltrimethoxysilane (MPTS). Depending on the reactants ratio, the particle sizes were found between 50 and 500 nm and the Zeta potential was varying between - 20 and - 5 mV. The particles dimensions and the Zeta Potential decreased with the increasing MPTS concentration from the system. This was explained through hydrophobic interactions between partners and trimethoxysilane.
