Molecular weight and dispersity affect chain conformation and pH-response in weak polyelectrolyte brushes
Tzu-Han Li, Megan L. Robertson, Jacinta C. Conrad
Abstract
The pH-dependence of the conformation of annealed polyelectrolyte brushes can be tuned by varying the molecular weight distribution, as characterized via weight-average molecular weight and dispersity.
