a
The expression behind the polyelectrolyte name refers to the pH of the solution at assembly (for PAH and PAA) or in the case of PDADMAC to the salt content of the solution. The number behind the brackets refers to the number of adsorbed polyelectrolyte double layers (DL), with one DL being a combination of one polycation and one polyanion layer.
b
Terminal layer: (−)=polyanion(PE−), (+)=polycation(PE+), and PEG=poly (ethylene glycol).
