However, developing efficient, scalable, and environmentally friendly strategies for fabricating such membranes remains a significant challenge. In this study, isotactic polypropylene (iPP) fibrous membranes with morphologies ranging from ellipsoidal stacking to microfiber stacking were successfully fabricated via a multistage stretching extrusion and leaching process using in situ microfibrillar composites (MFCs). The results establish a significant relationship between microfiber morphology and membrane oil adsorption performance. Compared with membranes formed from high-aspect-ratio microfibers, those comprising short microfibers feature larger pores and a more open structure, which enhances their oil adsorption capacity. Among the fabricated membranes, the iPP membrane with an ellipsoidal stacking morphology exhibits optimal performance, achieving a porosity of 65% and demonstrating both hydrophobicity and superoleophilicity, with a silicone oil adsorption capacity of up to 312.5%. Furthermore, this membrane shows excellent reusability and stability over ten adsorption\u2013desorption cycles using chloroform. This study presents a novel approach leveraging in situ microfibrillar composites to prepare high-performance oil\/water separation membranes in this study, underscoring their considerable promise for practical use.<\/jats:p>","DOI":"10.3390\/polym17152114","type":"journal-article","created":{"date-parts":[[2025,8,1]],"date-time":"2025-08-01T08:51:41Z","timestamp":1754038301000},"page":"2114","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Facile Preparation of iPP Fibrous Membranes from In Situ Microfibrillar Composites for Oil\/Water Separation"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3586-498X","authenticated-orcid":false,"given":"Chengtao","family":"Gao","sequence":"first","affiliation":[{"name":"Guizhou Material Industrial Technology Institute, Guiyang 550014, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Li","family":"Zhang","sequence":"additional","affiliation":[{"name":"Guizhou Material Industrial Technology Institute, Guiyang 550014, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xianrong","family":"Liu","sequence":"additional","affiliation":[{"name":"College of Electronic Information Engineering, Guiyang University, Guiyang 550005, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chen","family":"He","sequence":"additional","affiliation":[{"name":"College of Materials Science and Engineering, Guiyang University, Guiyang 550005, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shanshan","family":"Luo","sequence":"additional","affiliation":[{"name":"Guizhou Material Industrial Technology Institute, Guiyang 550014, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qin","family":"Tian","sequence":"additional","affiliation":[{"name":"College of Materials Science and Engineering, Guiyang University, Guiyang 550005, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,7,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"129900","DOI":"10.1016\/j.jhazmat.2022.129900","article-title":"A 3D smart wood membrane with high flux and efficiency for separation of stabilized oil\/water emulsions","volume":"441","author":"Wu","year":"2023","journal-title":"J.
