Network topology in magnetic gels studied by simulating the cross-linking process — •Rudolf Weeber and Christian Holm — Institut Fuer Computerphysik, Universitaet Stuttgart, Allmandring 3, 70569 Stuttgart

Ferrogels are hydrogels into which magnetic nanoparticles are immersed. Thereby,they combine elastic properties with the ability to react to external magnetic fields, which makes them candidates for applications such as drug delivery and actuation. One aspect of ferrogels, which is expected to have a large influence on their properties, is the topology of the polymer network forming the gel. This is, however, difficult to access experimentally. We therefore study the question using computer simulations. In the contribution, we present simulations of the cross-linking process of a magnetic gel, and we examine, how the resulting gel changes, depending on the conditions during cross-linking.
