The process involved the removal of lignin and the removal of hemicellulose utilizing NaOH concomitantly with the incorporation of ZnO and urea. Subsequently, an in situ reaction with boric acid was conducted to prepare flame-retardant wood aerogels. The morphology, chemical composition, thermal stability, and flame retardancy of the samples were studied. The results show that the NaOH treatment transformed the wood into a layered structure, and flame-retardant particles were uniformly distributed on the surface of the aerogel. The peak heat release rate (PHRR) and total heat release (THR) of the flame-retardant aerogel were significantly reduced compared with the control samples. Meanwhile, its vertical burning test (UL-94) rating reached the V-0 level, and the Limiting Oxygen Index (LOI) could exceed 90%. The flame-retardant wood aerogel exhibited excellent flame retardancy and self-extinguishing properties.<\/jats:p>","DOI":"10.3390\/ma17112638","type":"journal-article","created":{"date-parts":[[2024,5,30]],"date-time":"2024-05-30T03:45:08Z","timestamp":1717040708000},"page":"2638","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["A Top-Down Approach to the Fabrication of Flame-Retardant Wood Aerogel with In Situ-Synthesized Borax and Zinc Borate"],"prefix":"10.3390","volume":"17","author":[{"given":"Mingzeng","family":"Lin","sequence":"first","affiliation":[{"name":"School of Environmental and Natural Resources, Zhejiang University of Science and Technology, Hangzhou 310023, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiangkun","family":"Guo","sequence":"additional","affiliation":[{"name":"School of Environmental and Natural Resources, Zhejiang University of Science and Technology, Hangzhou 310023, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yinchao","family":"Xu","sequence":"additional","affiliation":[{"name":"School of Environmental and Natural Resources, Zhejiang University of Science and Technology, Hangzhou 310023, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xuejin","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Environmental and Natural Resources, Zhejiang University of Science and Technology, Hangzhou 310023, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Donghao","family":"Hu","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Shanghai Jiao Tong University, Shanghai 200030, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,5,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"224","DOI":"10.1016\/j.matdes.2018.08.031","article-title":"Low Density and High Strength Nanofibrillated Cellulose Aerogel for Thermal Insulation Application","volume":"158","author":"Gupta","year":"2018","journal-title":"Mater.
