Order and phase behavior of cylinder forming diblock copolymers and nano-particles mixture in confinement : A Molecular Dynamics study — •Lenin Singh Shagolsem1,2 and Jens-Uwe Sommer1,2 — 1Leibniz Institute of Polymer Research Dresden — 2Institute of Theoretical Physics, TU Dresden
We study a coarse grained model of cylinder forming diblock copolymers and nano-particles mixture confined between Lennard-Jones hard walls. Both non-selective and selective nano-particles cases are considered. For non-selective nano-particles two models of interactions between monomers and nano-particles are used. Here, we focused on the role of interfaces and particles clustering, uptake and segregation of particles as a function of temperature and overall particle volume fraction, and the influence of particles on morphology. On the other hand, for the case of selective nano-particles, we systematically explored the various ordered structures formed in this restricted environment.
