Phase behaviors of polymeric micelles by two different types polymers |
| 초록 |
The amphiphilic block copolymers self-assemble into a nanoscale micellar structure in solution, and their phase behavior can be controlled by external conditions. Therefore, Pluronic block copolymers can applicable for template materials to fabricate a variety of nanostructures. For a wide range of use, however, we need to fabricate various nanostructures without complicated procedures. Furthermore, we investigated the phase behavior of Pluronic block copolymers into mixture solution at varying temperatures with the controlled other polymer concentration as an additives. Small angle neutron scattering(SANS) experimental results showed that Pluronic block copolymers in aqueous solution transformed into spheres, cylinders or vesicles when the temperature, concentration and additives increase. As the temperature increase with the controlled other polymer concentration lead to an increase of the hydrophobicity of the polymer and then occur to phase transition. |
