We demonstrate a concept to produce deposits of polymer in the
form of particles by inkjet printing an emulsion in which the discrete phase
evaporates preferentially. An oil/water emulsion with polymer contained inside the
oil phase is used as ink for printing. Circular deposits of spherical polymer particles
with uniform thickness are obtained. The effects of the hydrophobicity of substrates
and the physical properties of the oil on the morphology of the deposits are
explored. The deposit of aggregated polymeric particles can be transformed into a
uniform film by annealing if required. This strategy for the patterning of polymer
materials in the form of either particles or a film works for mixtures of polymers and
functional cargoes.
