Nanocellulose Aerogels

Nanocellulose aerogelsNanocellulose aerogel have attracted attention in various fields because they have distinctive structures and properties, and are produced from abundant and sustainable precursors. In this chapter, we will summarize the development of aerogelsAerogels using nanocelluloseNanocellulose as a building blockBuilding blocks. First, we will describe the fabrication of nanocellulose aerogelsNanocellulose aerogel by freeze-dryingFreeze-drying, supercritical dryingSupercritical drying, and atmospheric pressure dryingAtmospheric pressure drying methods. Then, we will discuss how to control the structures, properties, and functions of the aerogelsAerogels via various strategies. Next, we will discuss the applicationApplication of aerogelsAerogels in energy storageEnergy storage, triboelectric nanogeneratorsTriboelectric nanogenerator, sensorsSensor, water purificationWater Purification, thermal insulationThermal insulation and scaffoldsScaffold, according to the characteristics of the aerogelsAerogels. Finally, we will describe the challenges and future trends associated with nanocellulose aerogelsNanocellulose aerogel from our personal perspective.
