英文摘要A new combined micromixer/microreactor/batch reactor system for the synthesis of monodisperse silica particles was demonstrated, which showed superiorities over the batch reactor. The silica nanoparticles with different sizes (ranging from 20 nm to 2 mu m) and size distributions could be controllably synthesized by varying the reaction temperature and reaction time. The narrowest size distribution of the silica particles was synthesized at 60 degrees C. The transmission electron microscopy characterization showed that the sphericities of silica particles got better as the particle size increased. Thermal gravimetry-differential thermal analysis and Fourier transform infrared characterization indicated that the amount of ethoxy groups of silica particles decreased and the hydroxyl groups increased with the reaction time increasing. And the hydroxyl groups in silica particles increased with the reaction temperature rising.
