摘要

在成功合成粉末状聚苯乙烯气凝胶（PPA）的基础上，详细研究了高分子纳米球构筑单元的结构和Friedel-Crafts超交联条件对PPA纳米结构的影响，初步考察了PPA对甲基红和亚甲基蓝的液相吸附性能。实验结果表明，PPA呈现三维纳米网络结构，其纳米球网络单元粒径约为30nm，且纳米球之间的堆叠形成大孔和中孔，从而具有独特的微孔-中孔-大孔层次化分布的孔结构特征。通过控制反应条件，其BET比表面积和总孔容可分别在201m

Abstract

On the basis of successful preparation of powdery polystyrene aerogel (PPA)

the influential factors on the nanostructure of PPA

for example

the structure of PSDVB nanospheres and the Friedel-Crafts hypercrosslinking conditions have been systematically investigated. The as-obtained PPA appears a hierarchical porous structure with 3D interconnected nano-networks comprising numerous nanospheres. The BET specific surface areas and total volume of PPA can be well controlled from 201m

respectively. Benefiting from the well-developed pore structure and strong hydrophobicity

PPA exhibits good adsorption performance towards methyl red in oily octane and methylene blue in water

respectively.
