【摘要】 <正> 胶囊化的无机颗粒因粘性和织构等有特殊的性质而在光学、药学和电子学等领域有着广泛的用途。最近,一种在液相系统中通过乳化聚合包覆无机超细颗粒(微米尺度)的方法得到了发展。另外,纳米无机颗粒因其特殊的性能而受到了广泛的关注,但纳米颗粒制备过程中最大的难题是更多还原

【Abstract】 Ecapsulation of silica nanoicles via dispersion polymerization of styrene is described. Silica nanoicles are synthesized by the Stober process and then modified by MPS. Approximate size of the silica nanoparticles is 30. 8 nm. By NMR spectrum it is shown that some polystyrene chains are then chemically bonded to the silica particles, through the coupling agent MPS.更多还原
