ABSTRACT : Atom transfer radical polymerization (ATRP) was applied to the synthesis of a microphase-separated amphiphilic graft copolymer brushes and amphiphilic cylindrical polymer brushes by using the “grafting from” technique. Amphiphilic graft copolymer brush consist of a poly(vinyl chloride) (PVC) backbone and poly(oxyethylene methacrylate) (POEM) side chains are self-assembled by ARTP to make up discrete nanophase domains of continuous PVC and isolated POEM region. This film is used to template the growth of silver nanoparticles in solid state. The selective incorporation and in situ formation of silver nanoparticles within the hydrophilic POEM domains will confirmed by some spectroscopy instruments. Well-defined amphiphilic core-shell cylindrical polymer brushes were used as single molecule templates, utilizing the coordination of cadmium ions with carboxylate groups in the core of the poly(acrylic acid)(PAA). Formation of CdS nanoparticles inside the polymer brush was carried out via the reaction of the coordinated Cd2+ ions with H2S. This route resulted in wire-like CdS nanoparticle assemblies.
Keywords : atom transfer radical polymerization(ATRP), nanoparticles, templates, spectroscopy.
