Effective interaction between star polymers
arXiv:cond-mat/9904444 · doi:10.1021/ma981844u
Abstract
The distance-resolved effective interaction between two star polymers in a good solvent is calculated by Molecular Dynamics computer simulations. The results are compared with a pair potential proposed recently by Likos et al. [Phys. Rev. Lett. 1998, 80, 4450] which is exponentially decaying for large distances and crosses over, at the corona diameter of the star, to an ultrasoft logarithmic repulsion for small distances. Excellent agreement is found in a broad range of star arm numbers.
