In the present study, the response of ionic microgels to crowding is investigated. The microgels in the charged and uncharged state are probed in concentrated suspensions consisting of either neutral and charged microgels. We combined small-angle X-ray scattering (SAXS) and small-angle neutron scattering (SANS) with contrast variation to obtain information on both particle-to-particle arrangement and response of individual microgels in the same suspensions. The results clearly show that domination of faceting or deswelling is determined by the charge state of the microgel and its surroundings. The dataset includes the following measurements: SAXS and SANS in diluted and concentrated suspensions, form factor fits to the SANS and SAXS data, dynamic light scattering (DLS) data, viscosimetry data.
