Electrophilic modification of polystyrene nanospheres.
Monodisperse polystyrene nanospheres synthesized via emulsifier-free emulsion polymerization were modified at their surfaces with amino and hydroxy groups using trimethylsilyl azide and bis(trimethylsilyl) peroxide, respectively, in the presence of trifluoromethanesulfonic acid. The acid chloride functionality was also introduced onto the surface using AlCl3-oxalyl chloride. The size, integrity, nature and functionality of the nanospheres were investigated by Scanning Electron Microscopy, diffuse reflectance IR and UV-Vis spectroscopy. The surface amino, hydroxyl and carboxylate groups were easily transformed into other useful functionalities by known methodologies.
