The fluorine-containing microporous membranes of the mainstream functional products easily cause harm to the environment, and thus, the fluorine-free environmental nanofibrous membranes are an important development direction for functional membranes. In this subject, the electrospun polyacrylonitrile nanofibrous membranes were first hydrophobically modified by amino functional modified polysiloxane (AMP), followed by in situ cross-linking modified with 4, 4\u2019-methyl diphenylene diisocyanate (MDI). The fluorine-free modification by AMP altered the surface of the membranes from hydrophilic to hydrophobic, and greatly improved the waterproof properties with the hydrostatic pressure reaching to 87.6 kPa. In addition, the formation of bonding points and the in situ preparation of polyuria through the reaction between the isocyanate in MDI and the amino group in AMP, could improve the mechanical properties effectively. When using AMP with the concentration of 1 wt% and MDI with the concentration of 2 wt%, the relatively good comprehensive performance was obtained with good water resistance (93.8 kPa), modest vapor permeability (4.7 kg m\u22122 d\u22121) and air permeability (12.7 mm\/s). Based on these testing data, the modified nanofibrous membranes had excellent waterproof and breathable properties, which has future potential in outdoor sports apparel.<\/jats:p>","DOI":"10.3390\/polym14235295","type":"journal-article","created":{"date-parts":[[2022,12,5]],"date-time":"2022-12-05T05:31:32Z","timestamp":1670218292000},"page":"5295","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Fluorine-Free Hydrophobic Modification and Waterproof Breathable Properties of Electrospun Polyacrylonitrile Nanofibrous Membranes"],"prefix":"10.3390","volume":"14","author":[{"given":"Ling","family":"Zhang","sequence":"first","affiliation":[{"name":"Nanotechnology Research Institute, College of Materials and Textile Engineering, Jiaxing University, Jiaxing 314001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Junlu","family":"Sheng","sequence":"additional","affiliation":[{"name":"Nanotechnology Research Institute, College of Materials and Textile Engineering, Jiaxing University, Jiaxing 314001, China"},{"name":"Key Laboratory of Yarn Materials Forming and Composite Processing Technology of Zhejiang Province, Jiaxing University, Jiaxing 314001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9548-1577","authenticated-orcid":false,"given":"Yongbo","family":"Yao","sequence":"additional","affiliation":[{"name":"Nanotechnology Research Institute, College of Materials and Textile Engineering, Jiaxing University, Jiaxing 314001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhiyong","family":"Yan","sequence":"additional","affiliation":[{"name":"Nanotechnology Research Institute, College of Materials and Textile Engineering, Jiaxing University, Jiaxing 314001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yunyun","family":"Zhai","sequence":"additional","affiliation":[{"name":"Jiaxing Key Laboratory of Molecular Recognition and Sensing, College of Biological, Chemical Sciences and Engineering, Jiaxing University, Jiaxing 314001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhongfeng","family":"Tang","sequence":"additional","affiliation":[{"name":"Shanghai Institute of Applied Physics, Chinese Academy of Sciences, Shanghai 201800, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haidong","family":"Li","sequence":"additional","affiliation":[{"name":"Nanotechnology Research Institute, College of Materials and Textile Engineering, Jiaxing University, Jiaxing 314001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1438","DOI":"10.1177\/0040517510392462","article-title":"Waterproof and breathable properties of nanoweb applied clothing","volume":"81","author":"Ahn","year":"2011","journal-title":"Text.
