  • Title: Effect of polydispersity on the phase diagrams of linear ABC triblock copolymers in two dimensions.
    Author: Jiang Y, Yan X, Liang H, Shi AC.
    Journal: J Phys Chem B; 2005 Nov 10; 109(44):21047-55. PubMed ID: 16853727.
    Abstract:
    By using a two-dimensional (2D) real-space self-consistent field theory, we present the phase diagrams of monodisperse ABC triblock copolymers in a three-component triangle style with the interaction energies given between the distinct blocks; this system displays richer phase behavior when compared with the corresponding diblock copolymers. Polydispersity of the end or middle blocks in the ABC linear block copolymer chains results in a completely different phase diagram. The presence of a polydisperse end block may cause strong segregation to occur among the three distinct components and larger domain sizes of the dispersed phases; a polydisperse middle block may allow a connection to form between the two phases of the two end blocks.
