摘要

•Temperature-induced changes in DN hydrogels investigated by SANS and 1H-NMR.•Two-component SANS profiles from DN hydrogels.•Change of PNIPAAm-water interaction with temperature reflected in SANS.•Water-rich and water-poor domains present in DN hydrogels at all temperatures.•PNIPAAm mobility in DN hydrogels reduced significantly at all temperatures.
