• 摘要： 隨著全球對可持續發展的重視，環保和可持續的生物可再生資源開發逐漸成為焦點。生物質氣凝膠，作為一種新型多孔材料，不僅具備傳統氣凝膠的卓越特性，如高機械強度、低密度、高孔隙率和大比表面積，而且還具有來源廣泛、無毒、生物兼容和可生物降解等獨特優點。然而，由于生物質材料表面富含親水性基團，容易吸水，導致氣凝膠結構破壞和力學性能降低，這對其實際應用穩定性造成影響。為此，近年來致力于對生物質氣凝膠進行改性和復合處理，并深入研究了改性機制，取得了顯著成果。本文從阻燃隔熱的角度，綜述了幾種常見生物質氣凝膠通過與聚合物、無機物復合，制備新型抗阻燃材料，并對其在阻燃領域的應用前景進行了展望，旨在為制備具有優良應用穩定性的新型生物質氣凝膠材料提供新思路。
• With the global emphasis on sustainable development, the development of environmentally friendly and sustainable bio-renewable resources has gradually become the focus. Biomass aerogel, as a new type of porous material, not only possesses the excellent characteristics of traditional aerogel, such as high mechanical strength, low density, high porosity and large specific surface area, but also has the unique advantages of being widely sourced, non-toxic, bioco-mpatible and biodegradable. However, as the surface of biomass materials is ri-ch in hydrophilic groups, they are prone to absorb water, leading to the destru-ction of aerogel structure and the reduction of mechanical properties, which affects the stability of their practical applications. For this reason, in recent years, we have devoted ourselves to the modification and composite treatment of bio-mass aerogels, and have studied the modification mechanism in depth, and have achieved remarkable results. In this paper, from the perspective of flame retardant insulation, several common biomass aerogels are reviewed to prepare new flame retardant materials by compounding with polymers and inorganic materias, and the prospect of their application in flame retardant field is also prospected, aiming to provide new ideas for the preparation of new biomass aerogel materials with excellent application stability.
