This composite process yielded PLA melt-blown\/electrospun composite materials with excellent filtration performance. The effects of the solution concentration and spinning duration on the composite structure and material performance were investigated. The optimal composite was produced using a 10 wt.% PLA spinning solution prepared with a solvent mixture of dichloromethane (DCM) and N, N-dimethylformamide (DMF) in a 75\/25 weight ratio. The process parameters included a spinning duration of 5 h, 18 kV voltage, 1.5 mL\/h flow rate, and 12 cm collection distance. The resulting composite achieved a filtration efficiency of 98.7%, a pressure drop of 142 Pa, an average pore size of 5 \u03bcm, and a contact angle of 138.7\u00b0. These results provided optimal process parameters for preparing PLA melt-blown\/electrospun composite filtration materials. This study highlights the potential of hydrophobic PLA composites with high filtration efficiency and low air resistance as environmentally friendly alternatives to traditional non-degradable filtration materials.<\/jats:p>","DOI":"10.3390\/polym17030424","type":"journal-article","created":{"date-parts":[[2025,2,6]],"date-time":"2025-02-06T06:30:29Z","timestamp":1738823429000},"page":"424","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["High-Efficiency and Low-Resistance Melt-Blown\/Electrospun PLA Composites for Air Filtration"],"prefix":"10.3390","volume":"17","author":[{"given":"Yongmei","family":"Guo","sequence":"first","affiliation":[{"name":"Fujian Key Laboratory of Novel Functional Textile Fibers and Materials, Clothing and Design Faculty, Minjiang University, Fuzhou 350108, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mingzhu","family":"Wu","sequence":"additional","affiliation":[{"name":"Fujian Key Laboratory of Novel Functional Textile Fibers and Materials, Clothing and Design Faculty, Minjiang University, Fuzhou 350108, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaojian","family":"Ye","sequence":"additional","affiliation":[{"name":"Fujian Key Laboratory of Novel Functional Textile Fibers and Materials, Clothing and Design Faculty, Minjiang University, Fuzhou 350108, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shengchao","family":"Wei","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Heavy Oil Processing, College of Chemical Engineering, China University of Petroleum (East China), Qingdao 266580, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luming","family":"Huang","sequence":"additional","affiliation":[{"name":"Fuzhou Chunhui Clothing Limited Company, Fuzhou 350108, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5211-5462","authenticated-orcid":false,"given":"Hailing","family":"Guo","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Heavy Oil Processing, College of Chemical Engineering, China University of Petroleum (East China), Qingdao 266580, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,2,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"152105","DOI":"10.1016\/j.cej.2024.152105","article-title":"Bio-based and bio-degradable nanofiber materials: A sustainable platform for energy, environmental, and biomedical applications","volume":"491","author":"Zhou","year":"2024","journal-title":"Chem.
