The phase behavior of blends of block copolymers (BCPs) is an interesting topic with respect to phase separation behavior. The phase behavior of BCP has been known to exhibit a microphase separation from an ordered to a disordered state either upon cooling or upon heating, where the latter behavior is called the order-disorder transition (ODT) with enthalpic origin, and the former can be induced by entropic origin, denoted to the lower disorder-order transition (LDOT). Therefore, if these block copolymers were fully miscible, the coexistence of phase transitions may be observed. In this study, we investigated the phase behavior in the blend of block copolymers, which have different type of phase behavior, using small angle X-ray scattering (SAXS), small angle neutron scattering (SANS), depolarized light scattering (DLS), and differential Scanning Calorimetry (DSC). |
