Figure 11. (a) Sorption and desorption kinetics plots (a = 0.4) for epoxy matrix at 24°C in terms of
normalized absorbance; (b) Sorption and desorption kinetics plots (a = 0.4) for polyimide matrix at
30°C in terms of normalized absorbance. (A(t) = absorbance at time t, A ∞ = absorbance at sorption
equilibrium).
