We analytically study the nonlinear force-extension relation of an array of parallel-aligned, strongly stretched semiflexible polymers with random cross-links. In the strong stretching limit, the effect of the cross-links is purely entropic, independent of the bending rigidity of the chains. Cross-links enhance the differential stretching stiffness of the bundle. For hard cross-links, the cross-link contribution to the force-extension relation scales inversely proportional to the force. Its dependence on the cross-link density, close to the gelation transition, is the same as that of the shear modulus. The qualitative behaviour is captured by a toy model of two chains with a single cross-link in the middle."],["dc.description.sponsorship","DFG [SFB 937]; EPSRC via the University of Cambridge TCM Programme Grant"],["dc.identifier.doi","10.1088/1367-2630/14/11/115011"],["dc.identifier.fs","591080"],["dc.identifier.isi","000311581600002"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/10186"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/24877"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Iop Publishing Ltd"],["dc.relation.issn","1367-2630"],["dc.relation.orgunit","Fakultät für Physik"],["dc.rights","CC BY 3.0"],["dc.title","Force-extension relation of cross-linked anisotropic polymer networks"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
