Figure 4. (a) Adsorption kinetics for the adsorption of PDADMAC onto a negatively
charged surface. The solid line is the best fitting to the equation 32. The two
components of the process are shown independently: - - - (fast process); (slow
process). (b) Long time representation as ln(Γ∞ - Γ) vs. time. (c) Short time
representation as ln(Γ∞ - Γ - A2e-t/τ2) vs. time.
4.3. Hydration Degree and Mechanichal Properties
of the Adsorbed Layers
Highly charged polyelectrolytes leads to less hidrated layers than low
charged ones [109, 119]. The water contained in the adsorbed layer
corresponds to hydration water around the loops and tails of adsorbed
