Effects of topology and size on statics and dynamics of complexes of hyperbranched polymers with linear polyelectrolytes

摘要

Brownian dynamics simulations with explicit hydrodynamic interactions have been employed to study generic effects of size and topology in noncovalent (Coulombic-driven) complexes formed by irregular-shaped hyperbranched polymers and linear polyelectrolytes.The behavior of the complexes was explored in detail in terms of static and dynamic properties,both in local and in the entire complex scale.The results were compared to previous studies on perfect dendrimers and other hyperbranched molecules where available.It was found that both molecular weight and structure may impart significant changes to key factors known to be associated with the ability of these systems to take part in relevant nanoscale applications.
