The effects of the CA\/PS ratio on fiber morphology, mechanical properties, porosity, wettability, air permeability, and thermal insulation were systematically investigated. Compared with the pure PS nanofibrous membranes, the CA\/PS (3\/1) membrane shows substantially enhanced structural and functional properties: porosity increases from 27.38% to 53.27%, air permeability from 56.45 \u00b1 3.71 mm\/s to 104.51 \u00b1 2.89 mm\/s, and water contact angle (WCA) from 124.79 \u00b1 3.21\u00b0 to 132.09 \u00b1 0.86\u00b0. Its tensile strength (5.38 \u00b1 0.47 MPa) and elongation at break (47.12 \u00b1 3.28%) are approximately 3.6 and 6.1 times those of the pure PS membrane (1.50 \u00b1 0.27 MPa and 7.67 \u00b1 1.61%). These prominent multifunctional characteristics enable the CA\/PS composite nanofibrous membranes to serve as promising candidates for personal protection, filtration and separation, and thermal management applications, although application-specific performance and long-term durability still require further investigations.<\/jats:p>","DOI":"10.3390\/ma19184000","type":"journal-article","created":{"date-parts":[[2026,9,21]],"date-time":"2026-09-21T17:23:17Z","timestamp":1790011397000},"page":"4000","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Preparation and Multifunctional Properties of Hydrophobic Electrospun Cellulose Acetate\/Polystyrene Nanofibrous Membranes"],"prefix":"10.3390","volume":"19","author":[{"given":"Zijia","family":"Wang","sequence":"first","affiliation":[{"name":"National Engineering Laboratory for Modern Silk, College of Textile and Clothing Engineering, Soochow University, 199 Ren-Ai Road, Suzhou 215123, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"conceptualization","vocabulary":"credit"},{"role":"methodology","vocabulary":"credit"},{"role":"formal-analysis","vocabulary":"credit"},{"role":"writing-original-draft","vocabulary":"credit"},{"role":"data-curation","vocabulary":"credit"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7026-8497","authenticated-orcid":false,"given":"Fujuan","family":"Liu","sequence":"additional","affiliation":[{"name":"National Engineering Laboratory for Modern Silk, College of Textile and Clothing Engineering, Soochow University, 199 Ren-Ai Road, Suzhou 215123, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"writing-review-editing","vocabulary":"credit"},{"role":"supervision","vocabulary":"credit"},{"role":"funding-acquisition","vocabulary":"credit"}]}],"member":"1968","published-online":{"date-parts":[[2026,9,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"5539","DOI":"10.1021\/acsnano.4c14213","article-title":"Fluorine-Free Nanofiber\/Network Membranes with Interconnected Tortuous Channels for High-Performance Liquid-Repellency and Breathability","volume":"19","author":"Ding","year":"2025","journal-title":"ACS Nano"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"124964","DOI":"10.1016\/j.memsci.2025.124964","article-title":"Engineering electrospun hydrophobic SiO2 nanofibers via organosilica-based click chemistry modification for ultrafast oil-water separation","volume":"740","author":"Wu","year":"2026","journal-title":"J.
