Fluorinated polysilsesquioxane (FPSQ) hollow spheres with a large empty interior were synthesized in an aqueous medium by using (trifluoropropyl)trimethoxysilane as the sole precursor. This fluorinated polysilsesquioxane hollow spheres were prepared for the first time with their applicability in drug release systems was demonstrated. The hollow spheres not only had a high surface coverage of the fluoroalkyl group (theoretically, 6.71 mmol/g), but also had a typical particle size of 192±12 nm, which is quite suitable for many applications, especially for controlled drug release systems. The monodispersed FPSQ hollow spheres had a high fluoroalkyl coverage surface and an empty interior, providing these materials with some potential applications, such as catalysts, gas separation, coating materials, nanoreactors and so on. |
