We demonstrate a simple and versatile approach to produce hierarchical assemblies of nanoparticles by combining block copolymers and small molecules. Directed nanoparticle assemblies can be achieved with a variety of nanoparticles and small molecules without modification of the nanoparticle ligands. This novel approach opens up new routes toward the fabrication of nanoparticle-based functional devices...
A variety of nanocomposites between metallic nanoparticles and polymers were produced. The attachment pattern of polymer micelles on the metal nanostructures evolved from the full coverage to partially engulfing, i. e. Janus (two-faced) nanoparticles, through tuning the ligand combinations. The basic principle for this achievement is that the surface feature is dictated by competitive chemisorption...
Conjugated polymers such as polyaniline (PANI) and poly(3,4-ethylenedioxythiophene) (PEDOT) were coated on Fe3O4 magnetic nanoparticles via two different methods. Core-shell Fe3O4-PANI nanocomposite was synthesized through graft polymerization, whereas Fe3O4-PEDOT nanocomposites were synthesized by insitu chemical oxidative polymerization. Resulted nanocomposites were characterized for structural,...
