abstract = {Exploiting soft, adaptive microgels as building blocks for
soft materials with controlled and predictable viscoelastic
properties is of great interest for both industry and
fundamental research. Here the flow properties of different
poly(N-isopropylacrylamide) (pNIPAM) microgels are compared:
regularly crosslinked versus ultra-low crosslinked (ULC)
microgels. The latter are the softest microgels that can be
produced via precipitation polymerization. The viscosity of
ULC microgel suspensions at low concentrations can be
described with models typically used for hard spheres and
regularly crosslinked microgels. In contrast, at higher
concentrations, ULC microgels show a much softer behavior
compared to regularly crosslinked microgels. The increase of
the storage modulus with concentration discloses that while
for regularly crosslinked microgels the flow properties are
mainly determined by the more crosslinked core, for ULC
microgels the brush-like interaction is dominant at high
packing fractions. Both the flow curves and the increase of
the storage modulus with concentration indicates that ULC
microgels can form glass and even reach an apparent jammed
state despite their extreme softness. In contrast, the
analysis of oscillatory frequency sweep measurements show
that when approaching the glass transition the ultra-low
crosslinked microgels behave as the regularly crosslinked
microgels. This is consistent with a recent study showing
that in this concentration range the equilibrium phase
behavior of these ULC microgels is the one expected for
regularly crosslinked microgels.},
