Size and shape controlled synthesis of binapthyl-based conjugated polymer/gold nanoparticle nanocomposites |
| 초록 |
Binapthyl-based conjugated polymers/gold nanoparticle (AuNP) hybrid nanocomposites were in-situ synthesized by the oxidation of polymer with auric acid. Bithiophene groups in the polymer reduced the Au(III) into Au(0) and the AuNPs can be stabilized by the polymer, especially through binapthyl groups of tweezer-like structure. The hydrodynamic radius of the polymer affects the size and shape of polymer/AuNPs hybrid nanocomposites. We investigated the polymer/AuNPs hybrid nanocomposites changing the molecular weight and hydrodynamic radi of the polymers in different solvent. The synthesized polymer/AuNPs hybrid nanocomposites were analysized by scanning electron microscope (SEM), transmission electron microscopy (TEM), dynamic light scattering (DLS), cyclic voltammetry (CV), and UV-vis spectroscopy. The polymers that have large hydrodynamic radii in solution formed large, multipod-like AuNPs structures and those with small hydrodynamic radii formed small, sphere-like AuNPs. |
