Good agreement between the quantitative theory and accurate exper‐ iments on the equilibrium phase behaviour of block copolymers has been achieved, and a thorough understanding has emerged by connecting the microscopic constituents to the mesoscopic phase structures and macroscopic material properties. Here, we review our current understanding of block copolymer phase behaviour, the standard model with its underlying assumptions, and present an overvi
