However, the complex manufacturing process associated with mechanical expansion leads to high production costs, limiting broader clinical adoption. In this study, we compared the structural, physicochemical, mechanical, and biological properties of porous PTFE barrier membranes fabricated by electrospinning and electrospraying with those of a commercially available ePTFE membrane, thereby providing a direct comparison of two distinct porous PTFE membrane architectures. The porous PTFE membranes were characterized using scanning electron microscopy, Fourier transform infrared spectroscopy, X-ray diffraction, tensile testing, contact angle goniometry, fibroblast cytotoxicity assays, and histological evaluation of the tissue response. The results showed that the fabrication methods produced markedly different membrane microstructures, which were associated with differences in tissue integration and inflammatory response. Both electrospinning and electrospraying were viable methods for producing non-cytotoxic PTFE barrier membranes with tunable structural properties. Notably, histological analysis revealed a favorable local tissue response and a limited inflammatory reaction to the electrospray fabricated PTFE membranes. Overall, these findings indicate that membrane microstructure ‒ including morphology, porosity, pore size, and surface topography ‒ is a major determinant of the biological performance of porous PTFE barrier membranes. They also provide a basis for the development of alternative PTFE barrier membranes for reconstructive surgery.</div></div>","PeriodicalId":357,"journal":{"name":"Journal of Fluorine Chemistry","volume":"294 ","pages":"Article 110630"},"PeriodicalIF":1.6,"publicationDate":"2026-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149347480","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
