Phase Transitions and Interaction Parameter behavior in quarternized Block Copolymer |
| 초록 |
Morphological transitions in an asymmetric, disordered poly (styrene-b-(2-vinylpyridine) block copolymer (BCP) were investigated by quarternizing the poly (2-vinylpyridine) block with an acid. The phase transitions of quarternized BCP from disorder-to-sphere-to-hexagonally packed cylindrical microphases were characterized by in-situ small angle x-ray scattering (SAXS) and transmission electron microscopy (TEM). The effective interaction parameter (χeff) between two block components was evaluated using Leibler theory based on the incompressible random phase approximation (RPA) for quarternized BCP in a disordered state. Thermal stability of the polyelectrolytes was also studied using thermo gravimetric analysis (TGA) and observed that acid shows prominent effect on thermal stability of BCP. |
