They influence the swelling/deswelling behaviour as well as the dynamics of the polymer chains. Scattering experiments provide insight into the polymer–water interaction of poly(N-isopropylacrylamide) (PNIPAM) microgels cross-linked with N,N′-methylenebisacrylamide (BIS) in dried and humidified state. The water mobility is studied by means of neutron spin-echo spectroscopy and neutron backscattering spectroscopy. The residual water amount has been determined with Karl Fischer titration. For both degrees of humidification, the relaxation time of the water molecules is much larger than that of free water due to the strong interactions with the polymer network and is only weakly depending on temperature and length scale of observation. The possible influence of the water on methyl group rotations is discussed 000893349 536__ $$0G:(DE-HGF)POF4-6G4$$a6G4 - Jülich Centre for Neutron Research (JCNS) (FZJ) (POF4-6G4)$$cPOF4-6G4$$fPOF IV$$x0 000893349 536__ $$0G:(DE-HGF)POF4-632$$a632 - Materials – Quantum, Complex and Functional Materials (POF4-632)$$cPOF4-632$$fPOF IV$$x1 000893349 536__ $$0G:(GEPRIS)290879244$$aDFG project 290879244 - Grenzflächennahe Dynamik nicht quervernetzter und quervernetzter Polymerarchitekturen auf festen planaren Oberflächen $$c290879244$$x2 000893349 588__ $$aDataset connected to CrossRef, Journals: juser.fz-juelich.de 000893349 65027 $$0V:(DE-MLZ)SciArea-210$$2V:(DE-HGF)$$aSoft Condensed Matter$$x0 000893349 65017 $$0V:(DE-MLZ)GC-1602-2016$$2V:(DE-HGF)$$aPolymers, Soft Nano Particles and Proteins$$x0 000893349 693__ $$0EXP:(DE-MLZ)J-NSE-20140101$$1EXP:(DE-MLZ)FRMII-20140101$$5EXP:(DE-MLZ)J-NSE-20140101$$6EXP:(DE-MLZ)NL2ao-20140101$$aForschungs-Neutronenquelle Heinz Maier-Leibnitz $$eJ-NSE: Neutron spin-echo spectrometer$$fNL2ao$$x0 000893349 693__ $$0EXP:(DE-MLZ)SPHERES-20140101$$1EXP:(DE-MLZ)FRMII-20140101$$5EXP:(DE-MLZ)SPHERES-20140101$$6EXP:(DE-MLZ)NL6S-20140101$$aForschungs-Neutronenquelle Heinz Maier-Leibnitz $$eSPHERES: Backscattering spectrometer$$fNL6S$$x1 000893349 7001_ $$0P:(DE-Juel1)184932$$aWitte, Judith$$b1$$ufzj 000893349 7001_ $$0P:(DE-HGF)0$$aLutzki, Jana$$b2 000893349 7001_ $$0P:(DE-Juel1)131056$$aZamponi, Michaela$$b3$$ufzj 000893349 7001_ $$0P:(DE-Juel1)184931$$aWellert, Stefan$$b4$$ufzj 000893349 7001_ $$0P:(DE-Juel1)130718$$aHolderer, Olaf$$b5 000893349 773__ $$0PERI:(DE-600)1476244-4$$a10.1039/D1CP01823J$$gp. 10.1039.D1CP01823J$$p14252-14259$$tPhysical chemistry, chemical physics$$v23$$x1463-9084$$y2021 000893349 8564_ $$uhttps://juser.fz-juelich.de/record/893349/files/d1cp01823j.pdf$$yOpenAccess 000893349 8767_ $$d2021-12-30$$eHybrid-OA$$jPublish and Read 000893349 909CO $$ooai:juser.fz-juelich.de:893349$$pdnbdelivery$$popenCost$$pVDB$$pVDB:MLZ$$pdriver$$popen_access$$popenaire 000893349 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)171604$$aForschungszentrum Jülich$$b0$$kFZJ 000893349 9101_ $$0I:(DE-HGF)0$$6P:(DE-Juel1)184932$$aExternal Institute$$b1$$kExtern 000893349 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)131056$$aForschungszentrum Jülich$$b3$$kFZJ 000893349 9101_ $$0I:(DE-HGF)0$$6P:(DE-Juel1)184931$$aExternal Institute$$b4$$kExtern 000893349 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)130718$$aForschungszentrum Jülich$$b5$$kFZJ 000893349 9131_ $$0G:(DE-HGF)POF4-6G4$$1G:(DE-HGF)POF4-6G0$$2G:(DE-HGF)POF4-600$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$aDE-HGF$$bForschungsbereich Materie$$lGroßgeräte: Materie$$vJülich Centre for Neutron Research (JCNS) (FZJ)$$x0 000893349 9131_ $$0G:(DE-HGF)POF4-632$$1G:(DE-HGF)POF4-630$$2G:(DE-HGF)POF4-600$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$aDE-HGF$$bForschungsbereich Materie$$lFrom Matter to Materials and Life$$vMaterials – Quantum, Complex and Functional Materials$$x1 000893349 9141_ $$y2021 000893349 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS$$d2021-01-28 000893349 915__ $$0StatID:(DE-HGF)0160$$2StatID$$aDBCoverage$$bEssential Science Indicators$$d2021-01-28 000893349 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000893349 915__ $$0StatID:(DE-HGF)1150$$2StatID$$aDBCoverage$$bCurrent Contents - Physical, Chemical and Earth Sciences$$d2021-01-28 000893349 915__ $$0LIC:(DE-HGF)CCBYNC3$$2HGFVOC$$aCreative Commons Attribution-NonCommercial CC BY-NC 3.0 000893349 915__ $$0StatID:(DE-HGF)0113$$2StatID$$aWoS$$bScience Citation Index Expanded$$d2021-01-28 000893349 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection$$d2021-01-28 000893349 915__ $$0StatID:(DE-HGF)9900$$2StatID$$aIF < 5$$d2021-01-28 000893349 915__ $$0StatID:(DE-HGF)0400$$2StatID$$aAllianz-Lizenz / DFG$$d2021-01-28$$wger 000893349 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bPHYS CHEM CHEM PHYS : 2019$$d2021-01-28 000893349 915__ $$0StatID:(DE-HGF)0430$$2StatID$$aNational-Konsortium$$d2021-01-28$$wger 000893349 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline$$d2021-01-28 000893349 915__ $$0StatID:(DE-HGF)0420$$2StatID$$aNationallizenz$$d2021-01-28$$wger 000893349 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List$$d2021-01-28 000893349 9201_ $$0I:(DE-Juel1)JCNS-FRM-II-20110218$$kJCNS-FRM-II$$lJCNS-FRM-II$$x0 000893349 9201_ $$0I:(DE-588b)4597118-3$$kMLZ$$lHeinz Maier-Leibnitz Zentrum$$x1 000893349 9201_ $$0I:(DE-Juel1)JCNS-4-20201012$$kJCNS-4$$lJCNS-4$$x2 000893349 9201_ $$0I:(DE-Juel1)JCNS-1-20110106$$kJCNS-1$$lNeutronenstreuung$$x3 000893349 9801_ $$aFullTexts 000893349 980__ $$ajournal 000893349 980__ $$aVDB 000893349 980__ $$aUNRESTRICTED 000893349 980__ $$aI:(DE-Juel1)JCNS-FRM-II-20110218 000893349 980__ $$aI:(DE-588b)4597118-3 000893349 980__ $$aI:(DE-Juel1)JCNS-4-20201012 000893349 980__ $$aI:(DE-Juel1)JCNS-1-20110106 000893349 980__ $$aAPC
