摘要

Bio-based aerogels are environmentally friendly and renewable materials that exhibit excellent compatibility. However, their development is constrained by poor flame retardancy and limited mechanical properties. This paper presents an overview of the characteristics, classification, preparation techniques, and engineering applications of bio-based aerogels. Based on the thermal insulation mechanism, this paper summarizes the research progress of five common bio-based aerogels and proposes the future development direction.
