采用不同量的四甲基氢氧化铵（TMA）对Fe 3 O 4磁性纳米粒子进行胶溶。电泳测量表明，磁性纳米颗粒的稳定性取决于所使用的TMA的量。在纳米粒子表面生长二氧化硅保护层后，合成了不同核数的Fe 3 O 4/SiO2复合核壳粒子。在最佳TMA用量下，制备出多分散性为10.8%的均匀Fe 3 O 4/SiO2复合核壳纳米粒子。(c)2005 Elsevier B. V.保留所有权利。
Different amounts of tetramethylammonium hydroxide (TMA) were employed to peptize the Fe3O4 magnetic nanoparticles. Electrophoresis measurements show that the stability of the magnetic nanoparticles is dependent on the amount of TMA used. After growth of the silica protection layer on the nanoparticle surface, Fe3O4/SiO2 composite core/shell particles with different number of cores were synthesized. Under the optimal amount of TMA used, uniform Fe3O4/SiO2 Composite core/shell nanoparticles with a poly-dispersivity of 10.8% were prepared. (c) 2005 Elsevier B.V. All rights reserved.
