Foam-like properties of bundled polymer networks — •Lukas Paul Weise, Tobias Alexander Kampmann, and Jan Kierfeld — TU Dortmund University, Germany

We simulate systems of mutually attractive semiflexible harmonic chain polymers in quasi-two dimensions with the event chain algorithm. An isotropic initialization of the system evolves into a network of densely packed bundles of polymers. The resulting structure aims to minimize the overall bundle length which gives rise to properties reminiscent of foams. We examine the applicability of laws and relations characterizing the structure of foams to the bundled polymer networks in order to assess to what extent the networks behave foam-like. The dynamics of the bundled networks are found to be very sensitive with respect to details of the polymer interactions via friction terms albeit qualitative resemblance to foams remains.
