The obtained fibers were characterized in terms of their morphological, structural and thermal properties. Pure FucoPol fibers could not be obtained due to FucoPol\u2019s low water solubility and a lack of molecular entanglements. Nanofibers were obtained via blending with PEO and pullulan. FucoPol:PEO (1:3 w\/w) showed fibers with well-defined cylindrical structure, since the higher molecular weight of PEO helps the continuity of the erupted jet towards the collector, forming stable fibers. WAXS, DSC and TGA showed that FucoPol is an amorphous biopolymer, stable until 220 \u00b0C, whereas FucoPol-PEO fibers were stable until 140 \u00b0C, and FucoPol:pullulan fibers were stable until 130 \u00b0C. Interestingly, blended components influenced one another in intermolecular order, since new peaks associated to intermolecular hierarchical assemblies were seen by WAXS. These results make FucoPol-based systems viable candidates for production of nanofibers for packaging, agriculture, biomedicine, pharmacy and cosmetic applications.<\/jats:p>","DOI":"10.3390\/nano12030498","type":"journal-article","created":{"date-parts":[[2022,1,31]],"date-time":"2022-01-31T08:20:29Z","timestamp":1643617229000},"page":"498","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Preparation and Characterization of Electrospun Polysaccharide FucoPol-Based Nanofiber Systems"],"prefix":"10.3390","volume":"12","author":[{"given":"Yuliana","family":"V\u00e1zquez-Gonz\u00e1lez","sequence":"first","affiliation":[{"name":"Novel Materials and Nanotechnology Group, Institute of Agrochemistry and Food Technology (IATA), Spanish Council for Scientific Research (CSIC), Calle Catedr\u00e1tico Agust\u00edn Escardino Benlloch 7, 46980 Paterna, Spain"},{"name":"Laboratorio Integral de Investigaci\u00f3n de Alimentos, Tecnol\u00f3gico Nacional de M\u00e9xico-Instituto Tecnol\u00f3gico de Tepic, Av.
