We investigated the spray deposition
and subsequent self-assembly
during drying of a polystyrene nanoparticle dispersion with in situ
grazing incidence small-angle X-ray scattering at high time resolution.
During the fast deposition of the dispersion and the subsequent evaporation
of the solvent, different transient stages of nanoparticle assembly
can be identified. In the first stage, the solvent starts to evaporate
without ordering of the nanoparticles. During the second stage, large-scale
structures imposed by the breakup of the liquid film are observable.
In this stage, the solvent evaporates further and nanoparticle ordering
starts. In the late third drying stage, the nanoparticles self-assemble
into the final layer structure.
