Synthesis of uniform PS-b-P2VP nanoparticles via reprecipitation and their use as sacrificial templates for inorganic hollow nanoparticles†
Abstract
Uniform PS-b-P2VP (polystyrene-block-poly-2-vinylpyridine) block copolymer nanoparticles were successfully synthesized using a simple reprecipitation method. The PS-b-P2VP nanoparticles could serve as sacrificial templates to generate silica and titania hollow nanoparticles of ∼100 nm size.
