For most cases a LbL film has a unique layer sequence that is strictly defined by
the deposition sequence (Figure 1.3). This indicates that LbL deposition should
be considered as an analog to a chemical reaction sequence. While a chemical
reaction takes part between different synthons and typically yields a unique
molecule after each step of a given synthesis, layer-by-layer deposition involves
the adsorption of a single species or mixture in each adsorption step and yields a
multilayer film with a defined layer sequence at the end of the film assembly.
While molecules are synthesized in several consecutive reaction steps, a multicomposite film is fabricated in several subsequent adsorption steps
