As a substrate, silicon with a poly(allylamine hydrochloride) (PAH) coating is used. The temperature dependence of the deswelling of the microgel particles was probed with atomic force microscopy (AFM). The inner structure of the adsorbed microgel particles was detected with grazing incidence small angle neutron scattering (GISANS). Small angle neutron scattering (SANS) on corresponding microgel suspensions was performed for comparison. Whereas the correlation length of the polymer network shows a divergence in the bulk samples, in the adsorbed microgel particles it remains unchanged over the entire temperature range. In addition, GISANS indicates changes in the particles along the surface normal. This suggests that the presence of a solid surface suppresses the divergence of internal fluctuations in the adsorbed microgels close to the volume phase transition. 000155632 536__ $$0G:(DE-HGF)POF2-451$$a451 - Soft Matter Composites (POF2-451)$$cPOF2-451$$fPOF II$$x0 000155632 536__ $$0G:(DE-HGF)POF2-54G24$$a54G - JCNS (POF2-54G24)$$cPOF2-54G24$$fPOF II$$x1 000155632 588__ $$aDataset connected to CrossRef, juser.fz-juelich.de 000155632 65027 $$0V:(DE-MLZ)SciArea-210$$2V:(DE-HGF)$$aSoft Condensed Matter$$x1 000155632 65027 $$0V:(DE-MLZ)SciArea-110$$2V:(DE-HGF)$$aChemistry$$x0 000155632 65017 $$0V:(DE-MLZ)GC-1602-2016$$2V:(DE-HGF)$$aPolymers, Soft Nano Particles and Proteins$$x2 000155632 65017 $$0V:(DE-MLZ)GC-150-1$$2V:(DE-HGF)$$aKey Technologies$$x1 000155632 65017 $$0V:(DE-MLZ)GC-140$$2V:(DE-HGF)$$aSoft Matter, Macromolecules, Complex fluids, Biophysics $$x0 000155632 693__ $$0EXP:(DE-MLZ)KWS2-20140101$$1EXP:(DE-MLZ)FRMII-20140101$$5EXP:(DE-MLZ)KWS2-20140101$$6EXP:(DE-MLZ)NL3ao-20140101$$aForschungs-Neutronenquelle Heinz Maier-Leibnitz $$eKWS-2: Small angle scattering diffractometer$$fNL3ao$$x0 000155632 7001_ $$0P:(DE-HGF)0$$aHertle, Yvonne$$b1 000155632 7001_ $$0P:(DE-HGF)0$$aRichter, Marcel$$b2 000155632 7001_ $$0P:(DE-HGF)0$$aMedebach, Martin$$b3 000155632 7001_ $$0P:(DE-HGF)0$$aMagerl, David$$b4 000155632 7001_ $$0P:(DE-HGF)0$$aWang, Weinan$$b5 000155632 7001_ $$0P:(DE-HGF)0$$aDemé, Bruno$$b6 000155632 7001_ $$0P:(DE-Juel1)130905$$aRadulescu, Aurel$$b7$$ufzj 000155632 7001_ $$0P:(DE-HGF)0$$aMüller-Buschbaum, Peter$$b8 000155632 7001_ $$0P:(DE-HGF)0$$aHellweg, Thomas$$b9 000155632 7001_ $$0P:(DE-HGF)0$$avon Klitzing, Regine$$b10 000155632 773__ $$0PERI:(DE-600)2005937-1$$a10.1021/la500390j$$gVol. 30, no. 24, p. 7168 - 7176$$n24$$p7168 - 7176$$tLangmuir$$v30$$x1520-5827$$y2014 000155632 8564_ $$uhttps://juser.fz-juelich.de/record/155632/files/FZJ-2014-04690.pdf$$yRestricted 000155632 909CO $$ooai:juser.fz-juelich.de:155632$$pVDB$$pVDB:MLZ 000155632 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)130905$$aForschungszentrum Jülich GmbH$$b7$$kFZJ 000155632 9132_ $$0G:(DE-HGF)POF3-551$$1G:(DE-HGF)POF3-550$$2G:(DE-HGF)POF3-500$$aDE-HGF$$bKey Technologies$$lBioSoft – Fundamentals for future Technologies in the fields of Soft Matter and Life Sciences$$vFunctional Macromolecules and Complexes$$x0 000155632 9132_ $$0G:(DE-HGF)POF3-623$$1G:(DE-HGF)POF3-620$$2G:(DE-HGF)POF3-600$$9G:(DE-HGF)POF3-6G4$$aDE-HGF$$bForschungsbereich Materie$$lVon Materie zu Materialien und Leben$$vFacility topic: Neutrons for Research on Condensed Matter$$x1 000155632 9131_ $$0G:(DE-HGF)POF2-451$$1G:(DE-HGF)POF2-450$$2G:(DE-HGF)POF2-400$$3G:(DE-HGF)POF2$$4G:(DE-HGF)POF$$aDE-HGF$$bSchlüsseltechnologien$$lBioSoft$$vSoft Matter Composites$$x0 000155632 9131_ $$0G:(DE-HGF)POF2-54G24$$1G:(DE-HGF)POF2-540$$2G:(DE-HGF)POF2-500$$3G:(DE-HGF)POF2$$4G:(DE-HGF)POF$$aDE-HGF$$bStruktur der Materie$$lForschung mit Photonen, Neutronen, Ionen$$vJCNS$$x1 000155632 9141_ $$y2014 000155632 915__ $$0StatID:(DE-HGF)0010$$2StatID$$aJCR/ISI refereed 000155632 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR 000155632 915__ $$0StatID:(DE-HGF)0110$$2StatID$$aWoS$$bScience Citation Index 000155632 915__ $$0StatID:(DE-HGF)0111$$2StatID$$aWoS$$bScience Citation Index Expanded 000155632 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection 000155632 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bThomson Reuters Master Journal List 000155632 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS 000155632 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline 000155632 915__ $$0StatID:(DE-HGF)0310$$2StatID$$aDBCoverage$$bNCBI Molecular Biology Database 000155632 915__ $$0StatID:(DE-HGF)0420$$2StatID$$aNationallizenz 000155632 915__ $$0StatID:(DE-HGF)1020$$2StatID$$aDBCoverage$$bCurrent Contents - Social and Behavioral Sciences 000155632 9201_ $$0I:(DE-Juel1)JCNS-1-20110106$$kNeutronenstreuung ; JCNS-1$$lNeutronenstreuung $$x0 000155632 9201_ $$0I:(DE-Juel1)JCNS-FRM-II-20110218$$kJCNS (München) ; Jülich Centre for Neutron Science JCNS (München) ; JCNS-FRM-II$$lJCNS-FRM-II$$x1 000155632 9201_ $$0I:(DE-Juel1)ICS-1-20110106$$kICS-1$$lNeutronenstreuung $$x2 000155632 980__ $$ajournal 000155632 980__ $$aVDB 000155632 980__ $$aI:(DE-Juel1)JCNS-1-20110106 000155632 980__ $$aI:(DE-Juel1)JCNS-FRM-II-20110218 000155632 980__ $$aI:(DE-Juel1)ICS-1-20110106 000155632 980__ $$aUNRESTRICTED 000155632 981__ $$aI:(DE-Juel1)IBI-8-20200312 000155632 981__ $$aI:(DE-Juel1)JCNS-1-20110106 000155632 981__ $$aI:(DE-Juel1)JCNS-FRM-II-20110218 000155632 981__ $$aI:(DE-Juel1)ICS-1-20110106
