Foamlike network of bundled semiflexible polymers — •Tobias A. Kampmann and Jan Kierfeld — TU Dortmund University, Germany

We applied the EC algorithm to a system of many (semiflexible) harmonic chains, where the simulation efficiency is comparable to optimized molecular dynamics simulations, while still incorporating the essential features of the actual dynamics. This algorithm allows the simulation of polymer melts, where reptation can be clearly observed. When the polymers interact via a short range, attractive square well potential bundled structures are assembled. We analyse time series of quasi-two-dimensional systems, where foam-like structures arise. This can be linked to the attractive interaction which leads to a minimization of the overall bundle length similar to surface tension in the case of foams. The low mobility and the bending stiffness of polymers lead to structural differences in comparison to soap foams.
