Universality of block copolymer melts.
Simulations of five different coarse-grained models of symmetric diblock copolymers are compared to demonstrate a universal (i.e., model-independent) dependence of the free energy and order-disorder transition (ODT) on the invariant degree of polymerization N̄. The actual values of χN at the ODT approach predictions of the Fredrickson-Helfand (FH) theory for N̄ ≳ 10(4) but significantly exceed FH...
متن کاملDensity Functional Theory for Block Copolymer Melts and Blends
We derive an expression for the free energy of the blends of block copolymers expressed as a functional of the density distribution of the monomer of each block. The expression is a generalization of the Flory-Huggins-de Gennes theory for homo polymer blends, and also a generalization of the Ohta-Kawasaki theory for the melts of diblock copolymers. The expression can be used for any blends of h...
متن کاملSelf-Consistent Field Theory for Melts of Low-Molecular-Weight Diblock Copolymer
This paper applies self-consistent field theory (SCFT) to discrete polymer chains consisting of a finite number of beads, N, joined together by freely jointed bonds of arbitrary potential, b(R). The numerics of this SCFT can be performed efficiently using spectral or pseudospectral algorithms, permitting its application to complex morphologies. To demonstrate its effectiveness, we examine diblo...
متن کاملPhase behaviour of block copolymer melts with arbitrary architecture
The Leibler theory [L. Leibler, Macromolecules 13 1602 (1980)] for mi-crophase separation in AB block copolymer melts is generalized for systems with arbitrary topology of molecules. A diagrammatic technique for calculation of the monomeric correlation functions is developed. The free energies of various mesophases are calculated within the second-harmonic approximation. Model highly-branched t...
متن کاملSelf-assembly of an ultra-high-molecular-weight comb block copolymer at the air–water interface
The self-assembly of a newly synthesized, amphiphilic comb block copolymer (CBCP) at the air–water interface was systematically explored using the Langmuir–Blodgett (LB) technique. The CBCP had an ultra-high molecular weight (Mw 1⁄4 510 10 g mol ) with polystyrene arms grafted along one block of long hydrophilic backbone. At the air–water interface, the CBCP molecules spontaneously assembled in...
