Stabilization of self-assemblednanostructures of amphiphilic copolymers |
| 초록 |
One fundamental problem with block copolymer micelles is their spontaneous dissociation at concentrations below their critical micelle concentration (CMC). Shell or Core cross linking method is general method to overcome this problem. We synthesized the Poly(ethylene glycol-block-succinimide) (PEG-b-PSI) amphiphilic block copolymers. The PEG-b-PSI amphiphilic block copolymers formed PEG corona spherical micelles in aqueous solution. PSI part of PEG-b-PSI was easily cross-linked by aminolysis reaction with hexamethylenediamine. The molecular structure was measured by 1H NMR spectroscopy. The fixed micelle structure of core cross-linked PEG-b-PSI micelles was measured by TEM. |
