  1. 26. Mechanisms Affecting Glassy Dynamics in Thin Polymer Films
    Prof. Connie Roth (Emory University)

    Invited Speaker / Conférencier invité
    Numerous studies have documented changes in the glass transition temperature (Tg) with decreasing thickness for thin polymer films less than ~100 nm in thickness. However, understanding of the fundamental mechanisms causing this phenomenon are still unknown. We have demonstrated that two separate mechanisms can act simultaneously to propagate enhanced mobility from the free surface deeper...

    Liquid bridges form when a liquid is stretched between two boundaries, creating a freestanding fiber. The break-up of simple Newtonian liquid bridges has been studied both theoretically and experimentally for a wide variety of different initial conditions since Plateau and Rayleigh considered the instability of a liquid jet. Though the break-up of liquid bridges composed of linear polymer...

  3. 98. Phase Behaviour of Polyelectrolyte/Homopolymer Blends

    Oral (Student, In Competition) / Orale (Étudiant(e), inscrit à la compétition)
    The phase behaviour of polyelectrolyte/homopolymer blends is studied using self-consistent field theory. The blends are composed of charged and neutral homopolymers plus counter ions dissociated from the polyelectrolytes. We explore the phase behaviour of the system as a function of blend composition, charge density and interaction parameter. Besides the usual macrophase separation behaviour,...

  4. 12. **WITHDRAWN** Monte Carlo Field-Theoretic Simulations for Melts of Diblock Copolymer
    Prof. Mark Matsen (University of Waterloo)
    17/06/2014, 14:45
    Condensed Matter and Materials Physics / Physique de la matière condensée et matériaux (DCMMP-DPMCM)
    Invited Speaker / Conférencier invité
    Monte Carlo field-theoretic simulations (MC-FTS) are performed on melts of symmetric diblock copolymer for polymerization indices extending down to experimentally relevant values. The simulations are performed with a fluctuating composition field and a pressure field that follows the saddle-point approximation. Our study focuses on the disordered-state structure function, S(k), and the...
