abstract = {The adsorption of ethylene glycol (EG) based microgel
particles at silicon surfaces was studied. Monodisperse
p-MeO2MA-co-OEGMA microgel particles were synthesized by
precipitation polymerization. Translational and inner
dynamics of p-ME3O5 and p-ME3O26 microgels in bulk were
investigated by dynamic light scattering (DLS) and neutron
spin echo spectroscopy in transmission geometry (NSE). Here,
cooperative diffusion and Zimm type dynamics were observed.
The inner dynamics of these microgel particles in adsorbed
state was explored by neutron spin echo spectroscopy under
grazing incidence (GINSES). The reported GINSES experiments
demonstrate the feasibility of these surface sensitive
measurements. It indicates a slowing down of the inner
dynamics in the vicinity of the substrate. At increasing
distance from the substrate, the relaxation is comparable to
the bulk.},
