X-ray diffraction measurements and Fourier-transform infrared spectroscopy indicated that there were no chemical interactions between BaFe12O19 and polypyrrole. In addition, scanning electron microscopy showed that the composites exhibited a core\u2013shell structure. Subsequently, the prepared nanocomposite was used as a filler to prepare a coating suitable for ultraviolet curing. The performance of the coating was investigated by evaluating its hardness, adhesion, absorbance, and resistance to acids and alkalis. Importantly, the addition of BaFe12O19-polypyrrole nanocomposites not only improved the coating hardness and adhesion but also produced a coating with a good microwave absorption performance. The results suggested that BaFe12O19\/PPy composite has a lower reflection loss peak and a larger effective bandwidth at the X band when the proportion of the absorbent sample is 5\u20137%, when the absorption performance is the best. The reflection loss is in the range of 8.88\u201310.92 GHz below \u221210 dB.<\/jats:p>","DOI":"10.3390\/polym15081839","type":"journal-article","created":{"date-parts":[[2023,4,11]],"date-time":"2023-04-11T01:33:03Z","timestamp":1681176783000},"page":"1839","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Preparation of a Microwave-Absorbing UV Coating Using a BaFe12O19-Polypyrrole Nanocomposite Filler"],"prefix":"10.3390","volume":"15","author":[{"given":"Ting","family":"Lai","sequence":"first","affiliation":[{"name":"Department of Materials and Chemistry, School of Environmental & Chemical Engineering, Nanchang Hangkong University, Nanchang 330063, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenzhen","family":"Qin","sequence":"additional","affiliation":[{"name":"Department of Materials and Chemistry, School of Environmental & Chemical Engineering, Nanchang Hangkong University, Nanchang 330063, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Caogui","family":"Cao","sequence":"additional","affiliation":[{"name":"Department of Materials and Chemistry, School of Environmental & Chemical Engineering, Nanchang Hangkong University, Nanchang 330063, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rong","family":"Zhong","sequence":"additional","affiliation":[{"name":"Department of Materials and Chemistry, School of Environmental & Chemical Engineering, Nanchang Hangkong University, Nanchang 330063, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yun","family":"Ling","sequence":"additional","affiliation":[{"name":"Department of Materials and Chemistry, School of Environmental & Chemical Engineering, Nanchang Hangkong University, Nanchang 330063, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2524-4231","authenticated-orcid":false,"given":"Yu","family":"Xie","sequence":"additional","affiliation":[{"name":"Department of Materials and Chemistry, School of Environmental & Chemical Engineering, Nanchang Hangkong University, Nanchang 330063, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,4,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"909","DOI":"10.1016\/j.compscitech.2010.02.002","article-title":"One-step synthesis, electromagnetic and microwave absorbing properties of a-FeOOH\/polyprrole nanocomposites","volume":"70","author":"Xiao","year":"2010","journal-title":"Compos.
