At a mass ratio of PAN:magnetite of 2:1, the total solid content in the dimethyl sulfoxide (DMSO) solution was varied between 15 wt.% and 25 wt.%, which represents the limits of the spinnable range. The results show that the most homogeneous nanofiber mats were 21 wt.% solid contents. At 15 wt.% solid contents, a nano-membrane with some fibrous regions was produced. Nanofibers at 25 wt.% had a much larger and more inhomogeneous diameter. Nevertheless, the magnetic properties of all samples were very similar, indicating that the distribution of magnetite nanoparticles in the fibers is comparable in all samples. The results also suggested that the samples spun from solutions with near-ideal solid contents (19–21 wt.%) contain agglomerations of the nanoparticles inside the nanofibers.\r\n "}],"status":"public","file_date_updated":"2024-02-24T07:59:57Z","publication_status":"published","has_accepted_license":"1","author":[{"full_name":"Graciano Alvarez, Ana Karen","first_name":"Ana Karen","last_name":"Graciano Alvarez"},{"last_name":"Dotter","full_name":"Dotter, Marius","first_name":"Marius","orcid":"0000-0001-8398-1809","id":"242889"},{"last_name":"Tuvshinbayar","first_name":"Khorolsuren","full_name":"Tuvshinbayar, Khorolsuren","id":"222971"},{"last_name":"Bondzio","full_name":"Bondzio, Laila","first_name":"Laila"},{"last_name":"Ennen","first_name":"Inga","full_name":"Ennen, Inga"},{"first_name":"Andreas","full_name":"Hütten, Andreas","last_name":"Hütten"},{"last_name":"Blachowicz","first_name":"Tomasz","full_name":"Blachowicz, Tomasz"},{"full_name":"Ehrmann, Andrea","first_name":"Andrea","last_name":"Ehrmann","orcid":"0000-0003-0695-3905","id":"223776"}],"publication_identifier":{"eissn":["2079-6439"]},"article_number":"19","doi":"10.3390/fib12030019","intvolume":" 12","type":"journal_article","oa":"1","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png"},"quality_controlled":"1","publication":"Fibers","issue":"3","article_type":"original","project":[{"name":"Institut für Technische Energie-Systeme","_id":"0ec202b7-cd76-11ed-89f4-a9e1a6dbdaa7"}],"date_created":"2024-02-24T08:00:29Z","title":"Electrospinning Poly(acrylonitrile) Containing Magnetite Nanoparticles: Influence of Magnetite Contents","_id":"4372","file":[{"date_created":"2024-02-24T07:59:57Z","relation":"main_file","success":1,"creator":"aehrmann","content_type":"application/pdf","file_size":35308642,"date_updated":"2024-02-24T07:59:57Z","file_name":"_2024_Graciano-Alvarez_Fibers12_19_v2.pdf","access_level":"open_access","file_id":"4373"}],"citation":{"chicago":"Graciano Alvarez, Ana Karen, Marius Dotter, Khorolsuren Tuvshinbayar, Laila Bondzio, Inga Ennen, Andreas Hütten, Tomasz Blachowicz, and Andrea Ehrmann. “Electrospinning Poly(Acrylonitrile) Containing Magnetite Nanoparticles: Influence of Magnetite Contents.” Fibers 12, no. 3 (2024). https://doi.org/10.3390/fib12030019.","alphadin":"Graciano Alvarez, Ana Karen ; Dotter, Marius ; Tuvshinbayar, Khorolsuren ; Bondzio, Laila ; Ennen, Inga ; Hütten, Andreas ; Blachowicz, Tomasz ; Ehrmann, Andrea: Electrospinning Poly(acrylonitrile) Containing Magnetite Nanoparticles: Influence of Magnetite Contents.

While the influence of bending radii on the magnetization reversal in such nanofibers was already discussed in the literature, the often occurring beads along the fibers have not yet been investigated in detail. It can be assumed that such beads will support domain wall formation due to a reduction of the relative impact of the shape anisotropy, in this way influencing magnetization reversal along the fiber. Here, we simulate magnetization reversal processes in iron, nickel, cobalt and magnetite fibers with a bead in the middle, produced in three typical dimensions gained by electrospinning. In most cases a vortex state occurs during magnetization reversal, independent from the material and the dimensions. For some angular orientations of the external magnetic field, double-vortex or meander states are visible, usually also followed by vortex states. These simulations underline the strong and highly reliable impact of beads along electrospun fibers, making these structures useful for data storage, transport and other applications."}],"doi":"10.1016/j.jmmm.2021.167855","citation":{"alphadin":"Amini, Fedi ; Blachowicz, Tomasz ; Ehrmann, Andrea: Systematic study of magnetization reversal in beaded fibers from different magnetic materials.

Inclusion of magnetic nanoparticles, for example, results in preparation of magnetic nanofibers which are usually isotropically distributed on the substrate. One method to create a preferred direction is using a spinning cylinder as the substrate, which is not always possible, especially in commercial electrospinning machines. Here, another simple technique to partly align magnetic nanofibers is investigated. Since electrospinning works in a strong electric field and the fibers thus carry charges when landing on the substrate, using partly conductive substrates leads to a current flow through the conductive parts of the substrate which, according to Ampère’s right-hand grip rule, creates a magnetic field around it. We observed that this magnetic field, on the other hand, can partly align magnetic nanofibers perpendicular to the borders of the current flow conductor. We report on the first observations of electrospinning magnetic nanofibers on partly conductive substrates with some of the conductive areas additionally being grounded, resulting in partly oriented magnetic nanofibers."}],"status":"public","file_date_updated":"2021-01-03T13:36:48Z","date_created":"2021-01-03T13:37:22Z","title":"Orientation of Electrospun Magnetic Nanofibers Near Conductive Areas","_id":"629","publication_status":"published","has_accepted_license":"1"}]
