Computer simulation of block copolymers under external fields — •A.V. Zvelindovsky — Centre for Materials Science, Department of Physics, Astronomy & Mathematics, University of Central Lancashire, Preston, PR1 2HE, United Kingdom

Physics of micro-phase separation in various block copolymer systems is investigated by means of dynamic self-consistent field simulation. The emphasis of this talk will be given on dynamics of systems subjected to external fields. Several examples will be discussed. The first example gives a picture of dynamic rearrangement of various structures (lamellar, hexagonally packed cylinders, spherical micelles) in the applied electric field. The second is illustrating kinetics of surface phase transitions in confined systems (thin films). Next, we discuss micro-phase transformation under temperature change. Results on soft confinement (vesicle formation and membrane fusion) will be reported as well.
