Using an electrostatic-based super inkjet printer
we report the high-resolution deposition of polyelectrolyte macroinitators
and subsequent polymer brush growth using SIARGET-
ATRP. We go on to demonstrate for the first time a submicron
patterning phenomenon through the addition of either a
like charged polyelectrolyte homopolymer or through careful
control of ionic strength. As a result patterning of polymer brushes
down to ca. 300 nm is reported. We present a possible mechanistic
model and consider how this may be applied to other polyelectrolyte-
based systems as a general method for sub-micron
