提出了一种在无添加剂条件下制备无团聚聚苯乙烯/二氧化硅核壳粒子的新方法。不同于其他报道通常使用液相合成方法，我们使用了电喷雾沉积方法。当其他方法使用添加剂将壳组分桥接并粘贴在芯材料上时，我们倾向于利用静电荷现象的作用来进行成功的涂覆过程。成功地制备了无团聚、粒径（80 ~ 300 nm）和形貌可控的纳米粒子。粒径和形态的控制也实现了通过仅改变PS核的大小和二氧化硅与PS的比例，分别。还描述了成功和不成功的条件，这对进一步开发（即扩大规模工艺）很重要。我们相信，这项研究将是有用的各种涂层应用。
A new method for the preparation of agglomeration-free core-shell polystyrene (PS)/silica particles under an additive-free process was proposed. Different from other reports that typically used a liquid-phase synthesis method, we used an electrospray deposition method. While other methods use additive to bridge and paste the shell component on the core material, we preferred to use the effect of electrostatic charge phenomenon to make successful coating process. The particles with agglomeration-free and controllable size (from 80 to 300nm) and morphology were successfully prepared. The control of particle size and morphology was also achieved by only changing the PS core size and the silica-to-PS ratio, respectively. The successful and unsuccessful condition was also described, which would be important for further developments (i.e. scale up process). We believe that this research would be useful for various coating applications.
