Formation of complex spherical packing phases in diblock copolymer/homopolymer blends

The formation and relative stability of spherical packing phases in binary blends composed of AB-diblock copolymers and A-homopolymers are systematically studied using the self-consistent field theory applied to the freely-jointed chain model of polymers. Phase diagrams with different model parameters of the blends are constructed, revealing that the emergence of various complex spherical packing phases, including the Frank-Kasper σ phase and …
