Abstract： Currently， the world is facing a prominent energy crisis and environmental pollution， making the development of new and efficient insulation materials a research hotspot. Cellulose-based composite aerogel is a new renewable thermal insulation material， its unique nano porous structure and low thermal conductivity endow it with excellent thermal insulation performance. The preparation methods， types and thermal insulation applications of cellulose-based composite aerogels are reviewed based on the types of nano cellulose， in order to improve energy utilization efficiency and reduce energy consumption.

Keywords： cellulose; aerogel; composite materials; thermal insulation
