On Microphase Separation of Block Copolymers In an Electric Field: Four Universal Classes

摘要: A microscopic statistical theory of homopolymer and copolymer melts in an electric field is developed. The nonlinear dielectric properties a melt are described, the dipole-dipole interaction between monomers being taken self-consistently into account. For diblocks, order-disorder transition studied framework random phase approximation. We predict that reveal four different universal types behavior under external fields: A, B, C D. To determine what class belongs to, only relevant parameters turn out to be: f, fraction chain, S (A) (B) , which characterize how many times radii gyration blocks B increase, respectively, along applied
