Symmetry breaking in particle-forming diblock polymer/homopolymer blends
TL;DR: This work uncovers a mechanism for generating Frank–Kasper phases in diblock copolymers with soft matrices that prefer to form a body-centered cubic structure in the neat-melt state and a particle-by-particle analysis of homopolymer partitioning furnishes a basis for understanding symmetry breaking.
