Interfacial Activity of Gold Nanoparticles Coated with a Polymeric Patchy Shell and the Role of Spreading Agents.

E d decreases and η d increases with the period because for higher periods, the perturbation is lower and the surface shows less elastic behavior. There is a clear trend of increasing E d and η d for decreasing A p for the 23 nm PPs, showing the elastic-shell behavior that becomes more important as there are more particles per unit of area.
