Electrospinning is a simple processing technique for producing fibers with diameters in the range of nanometers to a few micrometers. When using the different solvent ratios for this process, porous PS membranes are created due to nonsolvent and thermally induced phase separation (N\u2010TIPS). The morphology of the fibers is analyzed through scanning electron microscopy (SEM), which showed that fibers have diameters between 200\u00a0nm and 6\u00a0\u00b5m. SEM also revealed that the pores present on the surface of the fibers vary from densely compacted and well\u2010formed nanopores with diameters in the range of 20\u201350\u00a0nm to larger pores with sizes of \u2248100\u2013200\u00a0nm. The pore size varied with different solvent ratios. The surface area is analyzed using the Brunauer\u2013Emmett\u2013Teller (BET) method and found that the polymeric fibers have a high surface area (\u224835 m<jats:sup>2<\/jats:sup>\u00a0g<jats:sup>\u22121<\/jats:sup>). The fibers with such morphology are highly hydrophobic, with a contact angle higher than 143\u00b0. These materials are excellent candidates for applications in textiles, filtration, and biomedical fields.<\/jats:p>","DOI":"10.1002\/marc.202400403","type":"journal-article","created":{"date-parts":[[2024,9,26]],"date-time":"2024-09-26T15:59:33Z","timestamp":1727366373000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Influence of Mixed Solvent in the Morphology and Hydrophobicity of Electrospun Polystyrene Porous Fibers"],"prefix":"10.1002","volume":"45","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2008-8655","authenticated-orcid":false,"given":"Guilherme Henrique Fran\u00e7a","family":"Melo","sequence":"first","affiliation":[{"name":"Department of Chemical and Petroleum Engineering University of Calgary  2500 University Dr NW Calgary AB T2N 1N4 Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4124-3917","authenticated-orcid":false,"given":"Uttandaraman","family":"Sundararaj","sequence":"additional","affiliation":[{"name":"Department of Chemical and Petroleum Engineering University of Calgary  2500 University Dr NW Calgary AB T2N 1N4 Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,9,26]]},"reference":[{"key":"e_1_2_8_1_1","doi-asserted-by":"publisher","DOI":"10.3390\/polym15040921"},{"key":"e_1_2_8_2_1","first-page":"57","volume":"5","author":"Sabetzadeh N.","year":"2017","journal-title":"J.
