采用逐层（LBL）技术在室温下合成了聚苯乙烯（PS）核-介孔二氧化硅纳米粒子壳复合材料。通过X射线衍射(XRD)、透射电子显微镜(TEM)和扫描电子显微镜(SEM)对所得产物进行分析。结果表明，根据颗粒表面的电荷特性，逐层技术是合成复合材料的有效方法。实验还证实，可以控制核表面的覆盖百分比并定制壳厚度。
Polystyrene (PS) core–mesoporous silica nanoparticle shell composite has been synthesized with layer-by-layer (LBL) technique at room temperature. The obtained products were analyzed by X-ray diffraction (XRD), transmission electron microscopy (TEM) and scanning electron microscopy (SEM). The results showed that layer-by-layer technique was an effective method to synthesize the composite according to their charge character of the particles' surface. The experiments also confirmed that the coverage percentage of the core surface could be controlled and the shell thickness be tailored.
