Polymer Phase Behavior and Gold-Polymer Complex Nanostructure |
| 초록 |
In aqueous solution, the amphiphilic block copolymers are easily self-assembled a micelle. The polymer micelles can be controlled by external conditions as a temperature, additive and their mass fraction. The controlled micellar nanostructures can be used to the template for a different substance as a gold nanoparticle (AuNP). The poly(ethylene oxide)-poly(isopropyl glycidyl ether) diblock copolymer was synthesized by anionic ring-opening polymerization, and 4 nm AuNPs were synthesized by Brust method. The small angle x-ray scattering (SAXS) and cryogenic transmission electron microscope (cryo-TEM) measurements investigated that the phases of AuNP-polymer complex. As the results, the AuNPs formed various nanostructures. The AuNP-polymer formed the vesicular nanostructure without complicated procedures. The AuNP-polymer vesicle can be utilized as thermal sensors, imageable drug carriers, carriers for catalysts, and drug or enzyme delivery on the nano- and bio-science. |
