For this, we used two separate electrospinning methods with the goal of obtaining polymer complex composites with intact switching properties. In view of possible applications, we chose iron(II)-triazole-complexes that are known to exhibit spin crossover close to ambient temperature. Therefore, we used the complexes [Fe(atrz)3]Cl2 and [Fe(atrz)3](2ns)2 (2ns = 2Naphthalenesulfonate) and deposited those on fibers of polymethylmethacrylate (PMMA) and incorporated them into core\u2013shell-like PMMA fiber structures. These core\u2013shell structures showed to be inert to outer environmental influences, such as droplets of water, which we purposely cast on the fiber structure, and it did not rinse away the used complex. We analyzed both the complexes and the composites with IR-, UV\/Vis, M\u00f6ssbauer spectroscopy, SQUID magnetometry, as well as SEM and EDX imaging. The analysis via UV\/Vis spectroscopy, M\u00f6ssbauer spectroscopy, and temperature-dependent magnetic measurements with the SQUID magnetometer showed that the spin crossover properties were maintained and were not changed after the electrospinning processes.<\/jats:p>","DOI":"10.3390\/polym15102365","type":"journal-article","created":{"date-parts":[[2023,5,19]],"date-time":"2023-05-19T00:55:29Z","timestamp":1684457729000},"page":"2365","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Incorporation and Deposition of Spin Crossover Materials into and onto Electrospun Nanofibers"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-7173-1459","authenticated-orcid":false,"given":"Maximilian Seydi","family":"Kilic","sequence":"first","affiliation":[{"name":"Institute of inorganic Chemistry, Leibniz Universit\u00e4t Hannover, Callinstra\u00dfe 7, 30167 Hannover, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jules","family":"Brehme","sequence":"additional","affiliation":[{"name":"Institute of inorganic Chemistry, Leibniz Universit\u00e4t Hannover, Callinstra\u00dfe 7, 30167 Hannover, Germany"},{"name":"Faculty II, Hochschule Hannover, University of Applied Science an Arts, Ricklinger Stadtweg 120, 30459 Hannover, Germany"},{"name":"Hannover School for Nanotechnology, Laboratorium f\u00fcr Nano- und Quantenengineering (LNQE), Leibniz Universit\u00e4t Hannover, Schneiderberg 39, 30167 Hannover, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Justus","family":"Pawlak","sequence":"additional","affiliation":[{"name":"Institute of inorganic Chemistry, Leibniz Universit\u00e4t Hannover, Callinstra\u00dfe 7, 30167 Hannover, Germany"},{"name":"Hannover School for Nanotechnology, Laboratorium f\u00fcr Nano- und Quantenengineering (LNQE), Leibniz Universit\u00e4t Hannover, Schneiderberg 39, 30167 Hannover, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kevin","family":"Tran","sequence":"additional","affiliation":[{"name":"Institute of inorganic Chemistry, Leibniz Universit\u00e4t Hannover, Callinstra\u00dfe 7, 30167 Hannover, Germany"},{"name":"Hannover School for Nanotechnology, Laboratorium f\u00fcr Nano- und Quantenengineering (LNQE), Leibniz Universit\u00e4t Hannover, Schneiderberg 39, 30167 Hannover, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Friedrich Wilhelm","family":"Bauer","sequence":"additional","affiliation":[{"name":"Faculty II, Hochschule Hannover, University of Applied Science an Arts, Ricklinger Stadtweg 120, 30459 Hannover, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6834-6011","authenticated-orcid":false,"given":"Takuya","family":"Shiga","sequence":"additional","affiliation":[{"name":"Graduate School of Pure and Applied Sciences, University of Tsukuba, Tennodai 1-1-1, Tsukuba, Ibaraki 305-8577, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Taisei","family":"Suzuki","sequence":"additional","affiliation":[{"name":"Graduate School of Pure and Applied Sciences, University of Tsukuba, Tennodai 1-1-1, Tsukuba, Ibaraki 305-8577, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masayuki","family":"Nihei","sequence":"additional","affiliation":[{"name":"Graduate School of Pure and Applied Sciences, University of Tsukuba, Tennodai 1-1-1, Tsukuba, Ibaraki 305-8577, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ralf Franz","family":"Sindelar","sequence":"additional","affiliation":[{"name":"Faculty II, Hochschule Hannover, University of Applied Science an Arts, Ricklinger Stadtweg 120, 30459 Hannover, Germany"},{"name":"Hannover School for Nanotechnology, Laboratorium f\u00fcr Nano- und Quantenengineering (LNQE), Leibniz Universit\u00e4t Hannover, Schneiderberg 39, 30167 Hannover, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Franz","family":"Renz","sequence":"additional","affiliation":[{"name":"Institute of inorganic Chemistry, Leibniz Universit\u00e4t Hannover, Callinstra\u00dfe 7, 30167 Hannover, Germany"},{"name":"Hannover School for Nanotechnology, Laboratorium f\u00fcr Nano- und Quantenengineering (LNQE), Leibniz Universit\u00e4t Hannover, Schneiderberg 39, 30167 Hannover, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,5,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"5131","DOI":"10.1039\/D2MA00459C","article-title":"Thermal hysteresis of stress and strain in spin-crossover@polymer composites: Towards a rational design of actuator devices","volume":"3","author":"Martin","year":"2022","journal-title":"Mater.
