The chemical and structural properties of the polymer surface and bulk are studied in terms of plasma parameters (treatment time, power, and reactive gas flow rate). A good correlation between XPS and Fourier transform infrared spectroscopy analyses is demonstrated. The penetration depth of oxygen into the bulk of the polymer is investigated by angle resolved-XPS and time-of-flight SIMS","authors_text":"Fran\\c{c}ois Reniers, Laurent Houssiau, Nimer Wehbe, Perrine Leroy, Sami Abou Rich, Thierry Dufour","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.plasm-ph","submitted_at":"2016-04-29T12:36:54Z","title":"In-depth diffusion of oxygen into LDPE exposed to an Ar--O2 atmospheric post-discharge: a complementary approach between AR-XPS and Tof-SIMS techniques"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1604.08798","kind":"arxiv","version":1},"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":"sha256:2fc058a8bbe4e4d850d6e6309cacfce2a2eaf536341b76b0bfcd8fade5719a02","target":"record","created_at":"2026-05-18T01:16:01Z","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":"1e5cb90583295796740fcb1894aa5cb5b9948d494b855cc469df367ffa4c3d2d","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.plasm-ph","submitted_at":"2016-04-29T12:36:54Z","title_canon_sha256":"3bee439c76bcf841dd1a9f3a129307cb37a018fbfe5d8642682aa1e97357f60a"},"schema_version":"1.0","source":{"id":"1604.08798","kind":"arxiv","version":1}},"canonical_sha256":"e7afc10ba52a2efd262fa57d8007d6250e11f68d1364cca17ca6755a98113cf8","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"e7afc10ba52a2efd262fa57d8007d6250e11f68d1364cca17ca6755a98113cf8","first_computed_at":"2026-05-18T01:16:01.733921Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:16:01.733921Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"fI70XAxEnykpzrjBcapIfYrkQ1TpoDX6pjr2wSQhj07hRtteiJQG+mMBHQym/q8fNMNc3MCWIhOEDJb884WvCA==","signature_status":"signed_v1","signed_at":"2026-05-18T01:16:01.734499Z","signed_message":"canonical_sha256_bytes"},"source_id":"1604.08798","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:2fc058a8bbe4e4d850d6e6309cacfce2a2eaf536341b76b0bfcd8fade5719a02","sha256:731677b33dfa5f3f2fbbe6344dd8ac9359f3b1e71d1699a93a5dbac276e10051"],"state_sha256":"0954fcfc15d70ede861f5bb4df9a6fcd6cfdcf5014b21de16eb60c5db663209c"}
