Bio-derived flame retardants are gaining attention as environmentally friendly additives due to their low ecological impact and decreasing costs. These compounds can enhance char formation in polymeric materials by swelling upon heating, attributed to their functional groups. This review explores various biomolecules used as flame retardants, including phytic acid, chitosan, lignin, tannic acid, and bio-derived phosphorus and nitrogen compounds, emphasizing their flame-retardant properties and compatibility with different polymer matrices. The primary focus is on the structural characteristics, modifications, and flame-retardant behaviors of these bio-derived additives, particularly regarding their mechanisms of action within polymeric materials. Finally, the review explores the opportunities, current challenges, and future directions for the practical application of bio-derived flame retardants in polymer materials.<\/jats:p>","DOI":"10.3390\/polym17020249","type":"journal-article","created":{"date-parts":[[2025,1,20]],"date-time":"2025-01-20T07:47:37Z","timestamp":1737359257000},"page":"249","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":64,"title":["Recent Advancements of Bio-Derived Flame Retardants for Polymeric Materials"],"prefix":"10.3390","volume":"17","author":[{"given":"Min","family":"Chen","sequence":"first","affiliation":[{"name":"Fujian Provincial Key Laboratory of Functional Materials and Applications, School of Materials Science and Engineering, Xiamen University of Technology, Xiamen 361024, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qinhe","family":"Guo","sequence":"additional","affiliation":[{"name":"Fujian Provincial Key Laboratory of Functional Materials and Applications, School of Materials Science and Engineering, Xiamen University of Technology, Xiamen 361024, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yao","family":"Yuan","sequence":"additional","affiliation":[{"name":"Fujian Provincial Key Laboratory of Functional Materials and Applications, School of Materials Science and Engineering, Xiamen University of Technology, Xiamen 361024, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6364-1898","authenticated-orcid":false,"given":"Ao","family":"Li","sequence":"additional","affiliation":[{"name":"School of Mechanical and Manufacturing Engineering, University of New South Wales, Sydney, NSW 2052, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7195-6304","authenticated-orcid":false,"given":"Bo","family":"Lin","sequence":"additional","affiliation":[{"name":"School of Mechanical and Manufacturing Engineering, University of New South Wales, Sydney, NSW 2052, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yi","family":"Xiao","sequence":"additional","affiliation":[{"name":"Fujian Provincial Key Laboratory of Functional Materials and Applications, School of Materials Science and Engineering, Xiamen University of Technology, Xiamen 361024, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lulu","family":"Xu","sequence":"additional","affiliation":[{"name":"School of Chemical Engineering, University of New South Wales, Sydney, NSW 2052, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5788-6314","authenticated-orcid":false,"given":"Wei","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Mechanical and Manufacturing Engineering, University of New South Wales, Sydney, NSW 2052, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,1,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2107905","DOI":"10.1002\/adma.202107905","article-title":"Advanced flame-retardant methods for polymeric materials","volume":"34","author":"Liu","year":"2022","journal-title":"Adv.
