Abstract:
Many aspects of Chemical engineering research have undergone a paradigm shift in the past decade, with an increased emphasis on technological applications which propose the use of materials and devices created by controlling matter from the atomic scales to the bulk commodity level. This talk will focus on multicomponent polymeric materials (block copolymers, rod-coil polymers and mixtures like polymer blends), which have played a central role in enabling this paradigm shift in the context of polymeric materials. The desirable properties of such multicomponent polymers arise from their tendencies to exhibit compositionally inhomogeneous structures, and a key effort to face the challenges in product development focuses on achieving an ability to manipulate the compositional inhomogeneity. In this talk, I will discuss our recent researches on developing simulation tools that can predict the structure, morphology and flow behavior of such multicomponent polymers. In contrast to conventional („particle-based‰) Monte Carlo and Molecular dynamics approaches, our methods work at a coarse-grained (field-based) description of the system to predict the thermodynamics and dynamics of complex fluids. This talk will focus on an outline of the simulation strategies and present results concerning both the equilibrium and dynamical properties of such materials.
