The electrospinning was carried out using a chloroform\/n-Propyl-lactate (n-PL) binary solvent system with different chloroform\/nPL ratios, in order to control the morphology of the microfibres. With pure chloroform, porous and dumbbell shape fibres were obtained whereas, with the addition on n-PL, circular and thinner fibres have been produced due to the higher boiling point and the higher conductivity of n-PL. The electrospinning process conditions were investigated to evaluate their impact on the fibres\u2019 morphology. These microfibrous mats presented potential to be used as breathable\/waterproof materials, with a pore diameter of 11 \u03bcm, an air resistance of 25.10\u22127 m\u22121 and water breakthrough pressure of 50 mBar.<\/jats:p>","DOI":"10.3390\/membranes11060422","type":"journal-article","created":{"date-parts":[[2021,5,31]],"date-time":"2021-05-31T21:42:06Z","timestamp":1622497326000},"page":"422","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Control Over the Morphology of Electrospun Microfibrous Mats of a Polymer of Intrinsic Microporosity"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8921-4966","authenticated-orcid":false,"given":"Elsa","family":"Lasseuguette","sequence":"first","affiliation":[{"name":"School of Engineering, University of Edinburgh, Robert Stevenson Road, Edinburgh EH9 3FB, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Richard","family":"Malpass-Evans","sequence":"additional","affiliation":[{"name":"EaStCHEM School of Chemistry, University of Edinburgh, David Brewster Road, Edinburgh EH9 3FJ, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John M.","family":"Tobin","sequence":"additional","affiliation":[{"name":"EaStCHEM School of Chemistry, University of Edinburgh, David Brewster Road, Edinburgh EH9 3FJ, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Neil B.","family":"McKeown","sequence":"additional","affiliation":[{"name":"EaStCHEM School of Chemistry, University of Edinburgh, David Brewster Road, Edinburgh EH9 3FJ, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4025-1237","authenticated-orcid":false,"given":"Maria-Chiara","family":"Ferrari","sequence":"additional","affiliation":[{"name":"School of Engineering, University of Edinburgh, Robert Stevenson Road, Edinburgh EH9 3FB, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,5,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"56","DOI":"10.1016\/j.cis.2010.09.005","article-title":"Membranes and theoritical modelling of membrane distillation: A review","volume":"164","author":"Khayet","year":"2011","journal-title":"Adv.
