| Abstract: | Aerogels possess the characteristics of high porosity, large specific surface area and low density because of their consecutive 3D network and porous structure. Fabricating aerogels with nanomaterials can improve the porous structure and mechanical strength, and further endue aerogels with special features including high conductivity, low heat conductivity, high adsorption capacity, good sound insulation, etc. Therefore, aerogels based on nanomaterials have significant applications in the fields of energy storage, thermal insulation and materials adsorption. This review summarizes the fabrication, structure, properties and applications of aerogels based on nanomaterials with various morphology including nanoparticles, nanocelluloses, carbon nanofibers, carbon nanotubes and graphene in recent years. Finally, the future development of aerogels based on nanomaterials is pointed out. |
