abstract = {We report on the swelling of a polymeric network in doubly
thermoresponsive microgels. Silica-core double-shell and
hollow double-shell microgels made of an inner
poly(N-isopropylmethacrylamide) and an outer
poly(N-isopropylacrylamide) shell are studied by exploiting
the distinct temperature sensitivities of the polymers. The
swelling states of the two shells can be tuned by
temperature changes enabling three different swelling
states: above, below, and between the distinct volume phase
transition temperatures of the two polymers. This enables to
investigate the effect of different constraints on the
swelling of the inner network. Small-angle neutron
scattering with contrast variation in combination with
computer simulation discloses how the expansion of the inner
shell depends on the material and swelling state of its
constraints. In the presence of the stiff core, the
microgels show a considerable interpenetration of the
polymeric shells: the inner network expands into the outer
deswollen shell. This interpenetration vanishes when the
outer network is swollen. Furthermore, as predicted by our
computer simulations, an appropriate choice of cross-linking
density enables the generation of hollow double-shell
nanocapsules. Here, the inner shell undergoes a push–pull
effect. At high temperature, the collapsed outer shell
pushes the swollen inner network into the cavity. At lower
temperature, the swelling of the outer network contrary
pulls the inner shell back toward the external periphery.},
