Confinement is either realized in model porous materials or in polymer nanocomposites (PNC). The dynamics of such confined polymers is affected on the local segmental level, the level of entanglements as well as on global levels: (i) at the segmental level the interaction with the surface is of key importance. At locally repulsive surfaces compared to the bulk the segmental dynamics is not altered. Attractive surfaces slow down the segmental dynamics in their neighborhood but do not give rise to dead, glassy layers. (ii) Confinement generally has little effect on the inter-chain entanglements: both for weakly as well as for marginally confined polymers the reptation tube size is not changed. Only for strongly confined polymers disentanglement takes place. Similarly, in PNC at higher NP loading disentanglement phenomena are observed; in addition, at very high loading a transition from polymer caused topological constraints to purely geometrical constraints is observed. (iii) On the more global scale NSE experiments revealed important information on the nature of the interphase between adsorbed layer and bulk polymer. (iv) Polymer grafts at NP mutually confine each other, an effect that is most pronounced for one component NP. (v) Global diffusion of entangled polymers both in weakly and strongly attractive PNC is governed by the ratio of bottle-neck to chain size that characterizes the ‘entropic barrier’ for global diffusion. 000867523 536__ $$0G:(DE-HGF)POF3-6215$$a6215 - Soft Matter, Health and Life Sciences (POF3-621)$$cPOF3-621$$fPOF III$$x0 000867523 536__ $$0G:(DE-HGF)POF3-6G15$$a6G15 - FRM II / MLZ (POF3-6G15)$$cPOF3-6G15$$fPOF III$$x1 000867523 536__ $$0G:(DE-HGF)POF3-6G4$$a6G4 - Jülich Centre for Neutron Research (JCNS) (POF3-623)$$cPOF3-623$$fPOF III$$x2 000867523 588__ $$aDataset connected to CrossRef 000867523 65027 $$0V:(DE-MLZ)SciArea-210$$2V:(DE-HGF)$$aSoft Condensed Matter$$x0 000867523 65017 $$0V:(DE-MLZ)GC-1602-2016$$2V:(DE-HGF)$$aPolymers, Soft Nano Particles and Proteins$$x0 000867523 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 000867523 693__ $$0EXP:(DE-MLZ)KWS1-20140101$$1EXP:(DE-MLZ)FRMII-20140101$$5EXP:(DE-MLZ)KWS1-20140101$$6EXP:(DE-MLZ)NL3b-20140101$$aForschungs-Neutronenquelle Heinz Maier-Leibnitz $$eKWS-1: Small angle scattering diffractometer$$fNL3b$$x1 000867523 693__ $$0EXP:(DE-Juel1)SNS-NSE-20150203$$5EXP:(DE-Juel1)SNS-NSE-20150203$$eSNS-NSE: Neutron Spin Echo Spectrometer$$x2 000867523 7001_ $$0P:(DE-Juel1)130777$$aKruteva, Margarita$$b1 000867523 773__ $$0PERI:(DE-600)2191476-X$$a10.1039/C9SM01141B$$gVol. 15, no. 37, p. 7316 - 7349$$n37$$p7316 - 7349$$tSoft matter$$v15$$x1744-6848$$y2019 000867523 8564_ $$uhttps://juser.fz-juelich.de/record/867523/files/c9sm01141b.pdf$$yRestricted 000867523 8564_ $$uhttps://juser.fz-juelich.de/record/867523/files/c9sm01141b.pdf?subformat=pdfa$$xpdfa$$yRestricted 000867523 909CO $$ooai:juser.fz-juelich.de:867523$$pVDB$$pVDB:MLZ 000867523 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)130917$$aForschungszentrum Jülich$$b0$$kFZJ 000867523 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)130777$$aForschungszentrum Jülich$$b1$$kFZJ 000867523 9131_ $$0G:(DE-HGF)POF3-621$$1G:(DE-HGF)POF3-620$$2G:(DE-HGF)POF3-600$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$9G:(DE-HGF)POF3-6215$$aDE-HGF$$bForschungsbereich Materie$$lVon Materie zu Materialien und Leben$$vIn-house research on the structure, dynamics and function of matter$$x0 000867523 9131_ $$0G:(DE-HGF)POF3-6G15$$1G:(DE-HGF)POF3-6G0$$2G:(DE-HGF)POF3-600$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$9G:(DE-HGF)POF3-6G15$$aDE-HGF$$bForschungsbereich Materie$$lGroßgeräte: Materie$$vFRM II / MLZ$$x1 000867523 9131_ $$0G:(DE-HGF)POF3-623$$1G:(DE-HGF)POF3-620$$2G:(DE-HGF)POF3-600$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$9G:(DE-HGF)POF3-6G4$$aDE-HGF$$bForschungsbereich Materie$$lVon Materie zu Materialien und Leben$$vFacility topic: Neutrons for Research on Condensed Matter$$x2 000867523 9141_ $$y2019 000867523 915__ $$0StatID:(DE-HGF)0400$$2StatID$$aAllianz-Lizenz / DFG 000867523 915__ $$0StatID:(DE-HGF)0420$$2StatID$$aNationallizenz 000867523 915__ $$0StatID:(DE-HGF)0430$$2StatID$$aNational-Konsortium 000867523 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bSOFT MATTER : 2017 000867523 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS 000867523 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline 000867523 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List 000867523 915__ $$0StatID:(DE-HGF)0110$$2StatID$$aWoS$$bScience Citation Index 000867523 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection 000867523 915__ $$0StatID:(DE-HGF)0111$$2StatID$$aWoS$$bScience Citation Index Expanded 000867523 915__ $$0StatID:(DE-HGF)1150$$2StatID$$aDBCoverage$$bCurrent Contents - Physical, Chemical and Earth Sciences 000867523 915__ $$0StatID:(DE-HGF)9900$$2StatID$$aIF < 5 000867523 9201_ $$0I:(DE-Juel1)JCNS-FRM-II-20110218$$kJCNS-FRM-II$$lJCNS-FRM-II$$x0 000867523 9201_ $$0I:(DE-588b)4597118-3$$kMLZ$$lHeinz Maier-Leibnitz Zentrum$$x1 000867523 9201_ $$0I:(DE-Juel1)JCNS-1-20110106$$kJCNS-1$$lNeutronenstreuung$$x2 000867523 9201_ $$0I:(DE-Juel1)JCNS-2-20110106$$kJCNS-2$$lStreumethoden$$x3 000867523 980__ $$ajournal 000867523 980__ $$aVDB 000867523 980__ $$aI:(DE-Juel1)JCNS-FRM-II-20110218 000867523 980__ $$aI:(DE-588b)4597118-3 000867523 980__ $$aI:(DE-Juel1)JCNS-1-20110106 000867523 980__ $$aI:(DE-Juel1)JCNS-2-20110106 000867523 980__ $$aUNRESTRICTED
