Ring-Linear Mixtures of Semiflexible Rubber Bands

Abstract During the synthesis of ring polymers, mixtures and linear molecules are regularly obtained. Recent experiments simulations have shown that even small fractions can considerable modify shape rings, affecting its rheological response. Here we study blends semiflexible filaments, by using disordered assemblies open closed rubber bands. We analyze structure as a function length bands, composition means X-ray tomography. Contrary to what is observed in fully-flexible find increasing concentration bands may reduce average size rings ring-linear mixture. show this direct consequence reduction inter-ring threading, which naturally occurs when fraction decreases.
