Orientational order in two-dimensional random networks of semiflexible polymers — •Martin Kiemes1, Panayotis Benetatos2, and Annette Zippelius2 — 1Max-Planck-Institut für Dynamik und Selbstorganisation, Göttingen, Germany — 2Institut für Theoretische Physik, Universität Göttingen, Germany
It has recently been shown that in a 3D melt of semiflexible polymers random permanent cross-links that fix the corresponding segments to align give rise to orientationally ordered gels [1]. In the current work, using a similar semimicroscopic replica field-theoretic approach, we focus on the 2D case which allows us to consider cross-links that prescribe a finite angle between the corresponding segments. We discuss the resulting phase diagram in terms of the cross-link density, the polymer stiffness, and the crosslinking geometry.
