A self-consistent field approach for crosslinked polymer materials — •Friederike Schmid — KOMET 331, Institut fuer Physik, JGU Mainz

The Self-Consistent Field (SCF) theory is one of the most powerful approaches to studying inhomogeneous polymer melts and solutions. It is nowadays a standard method to calculate nanoscale structures at polymer-coated surfaces or at interfaces in polymer mixtures, self-organization of amphiphilic polymers, phase transitions between block copolymer mesophases, to name just a few examples. However, the original SCF theory has a major drawback: It can only treat polymeric fluids. Many polymeric materials have a network structure, which means that they respond elastically to stress and that deformations are restored. In the talk, a generalized SCF theory for networks shall be proposed. As a first application, it is used to study the effect of crosslinking on the order-disorder transition in ordered lamellar block copolymer phases.
