On the origins of the salt-concentration-dependent instability and lateral nanoscale heterogeneities of weak polyelectrolyte brushes : gradient brush experiment and Flory-type theoretical analysis
We investigated, by experiment and theory, the lateral structure of a weak polyelectrolyte brush at various added salt concentrations and chain grafting densities. Model poly(2-(dimethylamino)ethyl methacrylate) (PDMAEMA) brushes with grafting density gradients were developed for this study by using...
