超疏水、保温隔热、阻燃的生物质复合介孔气凝胶的制备与表征
Preparation and Characterization of Superhydrophobic,Thermally Insulating,Flame-Retardant,Mesoporous Bio-Composite Aerogel
摘要
Abstract
Aerogels have emerged as ideal alternatives to traditional thermal insulation materials and have received exten-sive attention.Silica aerogels have the advantages of high specific surface area,low density and low thermal conductivity,making them suitable for a wide range of applications.However,they have the disadvantage of low mechanical strength.In this study,ethyl silicate was used as the silicon source and cellulose nanofibrils as the reinforcing material to prepare a bio-mass composite aerogel through aging,modification and supercritical drying processes,and the resulting material was ana-lyzed and characterized.The results show that the biomass composite aerogel exhibits low density,high specific surface area and porosity,and a mesoporous structure,and also demonstrates advantageous properties including low thermal conductivity,superhydrophobicity,good thermal stability,and flame retardancy.These features position the material as a promising candidate for applications in aerospace,environmental protection,energy,chemical engineering,construction,textiles and related fields.关键词
