Brownian dynamics simulation of uniform comb polymers in two dimensions

Abstract

Brownian dynamics simulations are made for continuum, excluded, and nonexcluded volume, uniform H-comb polymers in two dimensions. It is found that the end-to-end distance and radius of gyration of the inner branches are expanded more than those of the outer branches for excluded volume combs. The ratio of the end-to-end distance scaling amplitudes appears to be a universal quantity in agreement with the conjecture of Gaunt et al.1 Moreover, the ratio of the radii of gyration scaling amplitudes seems to be universal.
