We use zwitterionic microgels as model systems for amphoteric microgels with an equal amount of positive and negative charges located in a defined distance. Using small angle neutron scattering (SANS), we measure the static structure factors, SM(q), of a series of zwitterionic microgels with increasing amount of zwitterion, including a reference sample of pure PNIPAM. The experimental SM(q) is compared with predictions based on the Percus-Yevick approximation for hard spheres. We also compare with the PNIPAM reference sample measured for zwitterionic microgels. We find no significant influence of the zwitterionic comonomer on the effective pair potential. The PNIPAM and the zwitterionic microgels can be described by the hard-sphere model for smaller volume fractions ϕT ≲ 0.4 only. 000171775 536__ $$0G:(DE-HGF)POF2-451$$a451 - Soft Matter Composites (POF2-451)$$cPOF2-451$$fPOF II$$x0 000171775 588__ $$aDataset connected to CrossRef, juser.fz-juelich.de 000171775 7001_ $$0P:(DE-Juel1)156528$$aRiest, Jonas$$b1$$ufzj 000171775 7001_ $$0P:(DE-HGF)0$$aEckert, Thomas$$b2 000171775 7001_ $$0P:(DE-HGF)0$$aLindner, Peter$$b3 000171775 7001_ $$0P:(DE-Juel1)130858$$aNaegele, Gerhard$$b4$$ufzj 000171775 7001_ $$0P:(DE-HGF)0$$aRichtering, Walter$$b5$$eCorresponding Author 000171775 773__ $$0PERI:(DE-600)2020854-6$$a10.1515/zpch-2014-0559$$gVol. 0, no. 0$$nISSN (Online) 2196-7156, ISSN (Print) 0942-9352$$p1033-1052$$tZeitschrift für physikalische Chemie$$v228$$x0942-9352$$y2014 000171775 8564_ $$uhttps://juser.fz-juelich.de/record/171775/files/%5BZeitschrift%20fr%20Physikalische%20Chemie%5D%20Comparison%20of%20the%20Microstructure%20of%20Stimuli%20Responsive%20Zwitterionic%20PNIPAM-co-Sulfobetaine%20Microgels%20with%20PNIPAM%20Microgels%20and%20Classical%20Hard-Sphere%20Systems.pdf$$yOpenAccess 000171775 8564_ $$uhttps://juser.fz-juelich.de/record/171775/files/%5BZeitschrift%20fr%20Physikalische%20Chemie%5D%20Comparison%20of%20the%20Microstructure%20of%20Stimuli%20Responsive%20Zwitterionic%20PNIPAM-co-Sulfobetaine%20Microgels%20with%20PNIPAM%20Microgels%20and%20Classical%20Hard-Sphere%20Systems.gif?subformat=icon$$xicon$$yOpenAccess 000171775 8564_ $$uhttps://juser.fz-juelich.de/record/171775/files/%5BZeitschrift%20fr%20Physikalische%20Chemie%5D%20Comparison%20of%20the%20Microstructure%20of%20Stimuli%20Responsive%20Zwitterionic%20PNIPAM-co-Sulfobetaine%20Microgels%20with%20PNIPAM%20Microgels%20and%20Classical%20Hard-Sphere%20Systems.jpg?subformat=icon-180$$xicon-180$$yOpenAccess 000171775 8564_ $$uhttps://juser.fz-juelich.de/record/171775/files/%5BZeitschrift%20fr%20Physikalische%20Chemie%5D%20Comparison%20of%20the%20Microstructure%20of%20Stimuli%20Responsive%20Zwitterionic%20PNIPAM-co-Sulfobetaine%20Microgels%20with%20PNIPAM%20Microgels%20and%20Classical%20Hard-Sphere%20Systems.jpg?subformat=icon-700$$xicon-700$$yOpenAccess 000171775 909CO $$ooai:juser.fz-juelich.de:171775$$pdnbdelivery$$pdriver$$pVDB$$popen_access$$popenaire 000171775 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)156528$$aForschungszentrum Jülich GmbH$$b1$$kFZJ 000171775 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)130858$$aForschungszentrum Jülich GmbH$$b4$$kFZJ 000171775 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 000171775 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 000171775 9141_ $$y2014 000171775 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection 000171775 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR 000171775 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS 000171775 915__ $$0StatID:(DE-HGF)0110$$2StatID$$aWoS$$bScience Citation Index 000171775 915__ $$0StatID:(DE-HGF)0111$$2StatID$$aWoS$$bScience Citation Index Expanded 000171775 915__ $$0StatID:(DE-HGF)9900$$2StatID$$aIF < 5 000171775 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000171775 915__ $$0StatID:(DE-HGF)1150$$2StatID$$aDBCoverage$$bCurrent Contents - Physical, Chemical and Earth Sciences 000171775 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline 000171775 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bThomson Reuters Master Journal List 000171775 920__ $$lyes 000171775 9201_ $$0I:(DE-Juel1)ICS-3-20110106$$kICS-3$$lWeiche Materie$$x0 000171775 9801_ $$aFullTexts 000171775 980__ $$ajournal 000171775 980__ $$aVDB 000171775 980__ $$aUNRESTRICTED 000171775 980__ $$aI:(DE-Juel1)ICS-3-20110106
