abstract = {Microgel particles of cross-linked poly(NIPAM-co-acrylic
acid) with different acrylic acid contents are investigated
in solution and in the adsorbed state. As a substrate,
silicon with a poly(allylamine hydrochloride) (PAH) coating
is used. The temperature dependence of the deswelling of the
microgel particles was probed with atomic force microscopy
(AFM). The inner structure of the adsorbed microgel
particles was detected with grazing incidence small angle
neutron scattering (GISANS). Small angle neutron scattering
(SANS) on corresponding microgel suspensions was performed
for comparison. Whereas the correlation length of the
polymer network shows a divergence in the bulk samples, in
the adsorbed microgel particles it remains unchanged over
the entire temperature range. In addition, GISANS indicates
changes in the particles along the surface normal. This
suggests that the presence of a solid surface suppresses the
divergence of internal fluctuations in the adsorbed
microgels close to the volume phase transition.},
