Using mean-field theory, we find that a strong short-range attraction between the two types of polymer chains is essential for the formation of multilayers. The dependence of the required short-range attraction on the polymer charge fraction and salt concentration is calculated. For weak short-range attraction between any two adjacent layers, the adsorbed amount (per added layer) decays as the distance from the surface increases, until the chains stop adsorbing altogether","authors_text":"Adi Shafir, David Andelman","cross_cats":["cond-mat.mtrl-sci"],"headline":"","license":"","primary_cat":"cond-mat.soft","submitted_at":"2005-09-06T16:21:59Z","title":"Polyelectrolyte multilayer formation: electrostatics and short-range interactions"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"cond-mat/0509157","kind":"arxiv","version":2},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:6f161e6cdc05031d04021d41719cd7b4fdeac8061cfe268ea0a060fe4de71fcb","target":"record","created_at":"2026-05-18T04:03:33Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"c3fcd5c86570e47f6a12b8f292d63930c91c945a6579185d6e3c15966c065492","cross_cats_sorted":["cond-mat.mtrl-sci"],"license":"","primary_cat":"cond-mat.soft","submitted_at":"2005-09-06T16:21:59Z","title_canon_sha256":"fc3822335d5e5c71144efb17f23e76a0c726be3ae3310ef73fa534f21b9a6267"},"schema_version":"1.0","source":{"id":"cond-mat/0509157","kind":"arxiv","version":2}},"canonical_sha256":"de2d3b6cdde490c60c9bc813c2a92b2639033aafb23f008ba9593569f190de29","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"de2d3b6cdde490c60c9bc813c2a92b2639033aafb23f008ba9593569f190de29","first_computed_at":"2026-05-18T04:03:33.004049Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T04:03:33.004049Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"93xka5c+78PCO5NXGmRBTqMMCiN6+wt39wIecromHBfgypESer7Q1ndND1bJ5u+9Fty6EHhwnCaI2MaSVBGtDw==","signature_status":"signed_v1","signed_at":"2026-05-18T04:03:33.004825Z","signed_message":"canonical_sha256_bytes"},"source_id":"cond-mat/0509157","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:6f161e6cdc05031d04021d41719cd7b4fdeac8061cfe268ea0a060fe4de71fcb","sha256:b2cd010fa735e8a6a0eb7c0be3d59fb034cc9bb482615f138937bca1fedfbb70"],"state_sha256":"1d9aa7dc429d6cdf7c46eb9d214e7d50976aed22639a339d90a117cbde7a4e33"}
