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...

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,...

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...
