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

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