Figure 3. Mean squared interchain center of mass distance as a function of chain rigidity for the double-tethered SC polymer model (“Two tethers”) as well as for the “null” model of free polymers (“Untethered”).

At low bending rigidity, double tethered SC polymers effectively form a “polymer brush”, leading to stronger segregation between them in contrast to the intermingling of free polymers. The shaded region indicates the range of bending rigidity that generates the experimentally observed mean squared center of mass distance of .
