Recently, many researchers have been studied to the preparation of polymeric nanoparticles with the size range larger than 50 nm by microemulsion polymerization. As for the formation of polymeric nanoparticles with free-surfactant, it has been found that block copolymers can self assemble into polymeric nanoparticles in a selective solvent in which only one block is soluble. In this study, poly(styrene)-b-poly(2-vinylpyridine) (PS-b-P2VP) was synthesized by living anionic polymerization. Also, the quaternized PS-b-P2VP diblock copolymer formed micelle-like polymeric nanoparticles. The size of polymeric nanoparticles was controlled as mole fraction of P2VP (fP2VP), molecular weight of diblock copolymer and solvents. We prepared the polymeric nanoparticles in the size range 10-50 nm and characterized by TEM and LS. |
