Study on Microstructure and Phase Transition ofPLA-PEG-PLA Tri-block Copolymer By SAXS & SANS |
| 초록 |
In recent years many efforts have been made in synthesis of PLA-PEG di- and tri-block copolymers. PLA-PEG block copolymers will self-assemble spontaneously in water into a spherical micelle of a few hundred molecules which has a core of densely packed hydrophobic PLA block and a dense PEG brush shell which radiates from the core. And they occur sol-gel transition by various concentrations and temperature. In this work, PLA-PEG-PLA tri-block copolymers with various block lengths were synthesized. The aqueous solutions of the synthesized block copolymers with different concentrations were prepared and their sol-gel transitions with the detailed microstructures accompanying the transition were examined by the small angle X-ray and neutron scattering (SAXS and SANS). |
