Molecular interpretation of scattering behavior of styrenic block copolymers |
| 초록 |
Scattering behavior of some block copolymers containing polystyrene is studied by small angle neutron scattering (SANS). The absolute scattering intensities and the resultant correlation lengths for the disordered samples are obtained as a function of temperature and pressure. The experimental scattering behavior is then analyzed by using random-phase approximation (RPA) analysis in connection with a molecular model for perturbed hard chains. Requisite molecular parameters are used to predict the scattering properties for the copolymers, which are compared with those measured by SANS. Effective Flory-type interaction is obtained and discussed with regard to its role in the scattering behavior for the copolymers. |
