Abstract:

As a new type of lightweight aerogel, the biomass cellulose carbon aerogel has unique isotropic 3D network and hierarchical porous structure. Based on the individual structure, the carbon aerogel owns the excellent properties of aerogel (high specific surface area, high porosity and low density), carbon materials (heat resistance and electrical conductivity) and biomass materials (biodegradable and biocompatible). In recent years, it has becomes one of the hotspot research fields in nano-functional materials. The raw material of biomass cellulose carbon aerogel is widely available, including plants (wood, bamboo, fruits and vegetables), marine life and bacteria. Based on the differences in raw material form, the preparation methods of biomass carbon aerogel are summarized as gel carbonization method and biomass direct carbonization method. In addition, this paper introduces the main properties and modified methods, such as light and more porous, hydrophobic, stability, electrical conductivity, and metal doping and heteroatom doping modification. These excellent material properties make it been widely used in the insulation, electrochemical, adsorption, and many other fields. Also, it is potential to be used more forward-looking emerging material fields, such as drug release, antimicrobial materials, tissue engineering and electromagnetic shielding. The functional preparation, characterization and application of biomass cellulose carbon aerogel are emerging. Based on the research, this paper discusses the prospective of biomass cellulose carbon aerogel. As a new type of green material, the biomass cellulose carbon aerogel provides an application prospect for high-value and functional application of biomass materials.
