Facile Synthesis of Metal Nanoparticles by Green Synthetic Protocols with Dumbbell-type Hyperbranched Polyglycidol |
초록 |
A series of dumbbell-type hyperbranched polyglycidol (dHBP) with different molecular weights have been synthesized via an anionic ring-opening multi-branching polymerization of glycidol using α,ω–amine terminated poly(propylene oxide) (molecular weight 230) as an initiator.The dHBP played role as an effective reducer and stabilizer for the synthesis of highly water-soluble monometallic (Au and Ag) nanoparticles in the absence of any additional reducers and surfactants. The dHBP-assisted reduction of metal ions follows an analogous polyol process. The size and shape of nanoparticles is controlled by simply changing the concentration of the metal ion precursor and dHBP dissolved. The optical properties of the as-prepared metal nanoparticles are investigated by UV-vis spectroscopy and their structural characteristics were defined by transmission electron microscope image. The size of these nanoparticles was measured by dynamic light scattering. |
