The obtained nanoparticles were able to develop into a ferrite (\u03b1-Fe) and \u03b1\u2033-Fe16N2 mixture with a superparamagnetic property and high saturated magnetization (SM) of 245 emu g\u22121 at 950 \u00b0C calcination under the protection of carbonization materials (calcined PANI) and other iron-compounds (\u03b1\u2033-Fe16N2). The SM of the calcined iron-composites slightly decreases to 232 emu g\u22121 after staying in the open air for 3 months. The calcined mixture composite can be ground into homogeneous powders without the segregation of the iron and carbon phases in the mortar without significantly losing magnetic activities.<\/jats:p>","DOI":"10.3390\/polym13142380","type":"journal-article","created":{"date-parts":[[2021,7,20]],"date-time":"2021-07-20T11:26:10Z","timestamp":1626780370000},"page":"2380","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Superparamagnetic, High Magnetic \u03b1-Fe &amp; \u03b1\u2033-Fe16N2 Mixture Prepared from Inverse Suspension-Polymerized Fe3O4@polyaniline Composite"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1701-3276","authenticated-orcid":false,"given":"Yen-Zen","family":"Wang","sequence":"first","affiliation":[{"name":"Department of Chemical and Materials Engineering, National Yu-Lin University of Science & Technology, Yun-Lin 640301, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu-Wei","family":"Cheng","sequence":"additional","affiliation":[{"name":"Department of Chemical Engineering, Ming Chi University of Technology, New Taipei City 24301, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1704-1629","authenticated-orcid":false,"given":"Lin-Chia","family":"Ho","sequence":"additional","affiliation":[{"name":"National Defense Medical Center, 161 Sec. 6 Minquan E.
