The change in the morphology after swelling was observed by SEM, while an FTIR analysis showed specific interactions between C-Ch and CP. Mechanical tests showed that C-Ch\/Ppy exhibited more elastic behavior and a better stress distribution compared to C-Ch\/Pani. The diffusion of Na+ and Ca2+ ions through the membranes was evaluated and showed a greater resistance for Ca2+ in both membrane types. Preliminary biocompatibility testing with H9C2 cells showed a successful cell adhesion to the membranes. These results emphasize the potential of C-Ch\/Pani composites for electrically active scaffolds and of C-Ch\/PPy composites for applications in mechanically dynamic tissue-specific regeneration.<\/jats:p>","DOI":"10.3390\/membranes15060177","type":"journal-article","created":{"date-parts":[[2025,6,11]],"date-time":"2025-06-11T08:18:06Z","timestamp":1749629886000},"page":"177","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Nanofibrous Membranes Based on Collagen and Conductive Polymers with Perspective for Biological Applications"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9699-684X","authenticated-orcid":false,"given":"Tonantzi","family":"P\u00e9rez-Moreno","sequence":"first","affiliation":[{"name":"Facultad de Ingenie\u00eda, Divisi\u00f3n de Investigaci\u00f3n y Posgrado, Universidad Aut\u00f3noma de Quer\u00e9rato, Santiago de Quer\u00e9taro 76010, Quer\u00e9taro, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Claudia","family":"D\u2019Urso","sequence":"additional","affiliation":[{"name":"Consiglio Nazionale delle Ricerche Istituto di Tecnologie Avanzate per l\u2019Energia \u201cNicola Giordano\u201d, Via S.
