Preparation of platinum nanoparticles in salt-induced micelles of dumbbell-shaped ABA copolymer.


The interaction of a water-soluble ABA type of dumbbell-shaped polyethyleniminated copolymers (D400(EI)8) with H2PtCl6 in aqueous medium is studied by means of UV-visible absorption spectra, dynamic light scattering (DLS) measurements, and transmission electron microscopy (TEM). From TEM images of the stained polymer, it is evident that the spherical and… (More)
