In this paper, resorcinol\u2013formaldehyde was introduced into the silicone network composed of methyltrimethoxysilane (MTMS), phenyltriethoxysilane (PTES), and dimethyldimethoxysilane (DMDMS). Flexible hybrid aerogels with excellent thermal insulation, flame retardant, and hydrophobic properties were prepared by the sol\u2013gel method and ambient pressure drying (APD), and the preparation process does not require long-term solvent exchange, only about 3 h of soaking and washing of the wet gel. The results show that the prepared phenolic-silicone aerogel has low density (0.093 g\/cm3), low thermal conductivity (0.041 W\/m\u00b7K), high flexibility, and compression fatigue resistance. The phenolic microspheres are bonded to the silicone skeleton to maintain the original flexibility. After 50% compression deformation, it returns to the original size normally, and there is no significant change in the stress of the sample after 50 compression cycles. Compared with pure silicone aerogels, the hybrid aerogels doped with phenolic have better char yield (65.28%) and higher decomposition temperature (609 \u00b0C). The hybrid aerogel sample has good flame-retardant properties, which can withstand alcohol lamp burning without being ignited. The micron-sized phenolic beads give the hybrid aerogels better hydrophobic properties, showing a higher static water contact angle (152\u00b0). The excellent thermal and mechanical properties mean that the hybrid aerogels prepared in this paper have good application prospects for aerospace, outdoor equipment, and other fields.<\/jats:p>","DOI":"10.3390\/molecules30030464","type":"journal-article","created":{"date-parts":[[2025,1,21]],"date-time":"2025-01-21T11:47:32Z","timestamp":1737460052000},"page":"464","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Facile Preparation of Flexible Phenolic-Silicone Aerogels with Good Thermal Stability and Fire Resistance"],"prefix":"10.3390","volume":"30","author":[{"given":"Zengyue","family":"Su","sequence":"first","affiliation":[{"name":"College of Textile and Engineering, TianGong University, Tianjin 300387, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3527-6467","authenticated-orcid":false,"given":"Zhenrong","family":"Zheng","sequence":"additional","affiliation":[{"name":"College of Textile and Engineering, TianGong University, Tianjin 300387, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaobiao","family":"Zuo","sequence":"additional","affiliation":[{"name":"National Engineering Research Center of Functional Carbon Fiber Composition Materials, Beijing 100076, China"},{"name":"Aerospace Research Institute of Materials and Processing Technology, Beijing 100076, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lijuan","family":"Luo","sequence":"additional","affiliation":[{"name":"Aerospace Research Institute of Materials and Processing Technology, Beijing 100076, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yaxin","family":"Guo","sequence":"additional","affiliation":[{"name":"College of Fine Arts, Linyi University, Linyi 276000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,1,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"102189","DOI":"10.1016\/j.cis.2020.102189","article-title":"An overview on alumina-silica-based aerogels","volume":"282","author":"Almeida","year":"2020","journal-title":"Adv.
