In a variation to the deposition by adsorption from solution, the application of layers
by spraying was introduced by L. Winterton [51] and J. Schlenoff [52] and the use of
spin-coaters was demonstrated by J.-D. Hong [53, 54] and also by H.-L. Wang [55, 56].
Both spraying and spin coating have the advantage that only small amounts of liquids
are needed to coat large surface areas. More importantly, both techniques can lead to
an enormous gain in deposition speed. We have recently shown that this reduction in
deposition speed by spray-assisted assembly [15] does lead to well ordered LbL-films
[16] and does not lead to a degradation of the nanostratification of such sprayassembled films (Figure 1.8).
