Therefore, they are interesting for a variety of possible applications, and it is convenient to integrate them into polymers. Due to a reduction of the iron content and thus also 57Fe content in the sample through integration in polymers, M\u00f6ssbauer measurements are only possible with greater difficulty or very long measurement times without expensive enrichment of the samples with 57Fe. So, other ways of improving the M\u00f6ssbauer signal for these composite materials are necessary. Therefore, we pressed these composite materials to improve the M\u00f6ssbauer spectra. In this study, we synthesized an iron(II) triazole spin crossover complex and an electrospun polymer complex composite nanofiber material including the same complex. For both products, M\u00f6ssbauer measurements were performed at room temperature before and after using a press to show that the complex composite is not harmed through pressing. We investigate the influence of the pressing impact on the M\u00f6ssbauer measurements in the context of measurement statistics and the measured signals. We show that pressing is not connected to any changes in the sample regarding the spin and oxidation state. We present that pressing improves the statistics of the M\u00f6ssbauer measurements significantly. Furthermore, we use SEM measurements and PXRD to investigate whether or not the obtained fiber mats are destroyed in the pressing process.<\/jats:p>","DOI":"10.3390\/polym16101311","type":"journal-article","created":{"date-parts":[[2024,5,7]],"date-time":"2024-05-07T11:00:10Z","timestamp":1715079610000},"page":"1311","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Pressing of Functionalized Polymer Composite Materials to Improve M\u00f6ssbauer Measurement Signals"],"prefix":"10.3390","volume":"16","author":[{"given":"Justus","family":"Pawlak","sequence":"first","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"},{"name":"Faculty I, Hochschule Hannover, University of Applied Science an Arts, Ricklinger Stadtweg 120, 30459 Hannover, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jules","family":"Brehme","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"},{"name":"Faculty II, Hochschule Hannover, University of Applied Science an Arts, Ricklinger Stadtweg 120, 30459 Hannover, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-7173-1459","authenticated-orcid":false,"given":"Maximilian Seydi","family":"Kilic","sequence":"additional","affiliation":[{"name":"Institute of Inorganic Chemistry, Leibniz Universit\u00e4t Hannover, Callinstra\u00dfe 7, 30167 Hannover, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"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":[{"role":"author","vocabulary":"crossref"}]},{"given":"Justin","family":"Koch","sequence":"additional","affiliation":[{"name":"Institute of Inorganic Chemistry, Leibniz Universit\u00e4t Hannover, Callinstra\u00dfe 7, 30167 Hannover, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohammad","family":"Beyki","sequence":"additional","affiliation":[{"name":"Hannover School for Nanotechnology, Laboratorium f\u00fcr Nano-und Quantenengineering (LNQE), Leibniz Universit\u00e4t Hannover, Schneiderberg 39, 30167 Hannover, Germany"},{"name":"Faculty I, Hochschule Hannover, University of Applied Science an Arts, Ricklinger Stadtweg 120, 30459 Hannover, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ralf","family":"Sindelar","sequence":"additional","affiliation":[{"name":"Hannover School for Nanotechnology, Laboratorium f\u00fcr Nano-und Quantenengineering (LNQE), Leibniz Universit\u00e4t Hannover, Schneiderberg 39, 30167 Hannover, Germany"},{"name":"Faculty II, Hochschule Hannover, University of Applied Science an Arts, Ricklinger Stadtweg 120, 30459 Hannover, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert","family":"Patzke","sequence":"additional","affiliation":[{"name":"Hannover School for Nanotechnology, Laboratorium f\u00fcr Nano-und Quantenengineering (LNQE), Leibniz Universit\u00e4t Hannover, Schneiderberg 39, 30167 Hannover, Germany"},{"name":"Faculty I, Hochschule Hannover, University of Applied Science an Arts, Ricklinger Stadtweg 120, 30459 Hannover, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1494-1242","authenticated-orcid":false,"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":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,5,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"15","DOI":"10.1002\/zaac.201100416","article-title":"Fifty years of M\u00f6ssbauer spectroscopy in solid state research\u2014Remarkable achievements, future perspectives","volume":"638","year":"2012","journal-title":"Z.
