CdS/polystyrene block copolymer nanocomposites modified with polar functional groups

CdS nanoparticles were prepared using polar functional polystyrene block copolymers. By modifying the polystyrene block copolymer with polar functional groups, the interaction between a polymer and nanoparticles could be improved, resulting in a higher fluorescence quantum yield of CdS nanoparticles. UV-Vis spectra and TEM images of CdS/polar functionalized block copolymer nanocomposites indicated the formation of nanoparticles with an average size of ∼5 nm.
