NOVELTY - Preparation of aerogel electrode material involves dispersing and mixing wood fiber, nano-crystalline cellulose, and crosslinking aid in water to provide the suspension that is dried to obtain wood fiber/nano-crystalline cellulose aerogel, performing crosslinking reaction of aerogel, adding polyaniline to aerogel, and injecting carboxylated carbon nanotube and/or oxidation graphene dispersion liquid into aerogel, and filtering, washing and drying to form positively and negatively charged polyaniline carboxylase glycosylated carbon nanotubes and/or graphene oxide on aerogel. USE - Preparation of aerogel electrode material (claimed). DETAILED DESCRIPTION - Preparation of aero-gel electrode material involves dispersing and mixing wood fiber, nano-crystalline cellulose, and crosslinking aid in water to provide the suspension, placing suspension into the container for freezing, and drying the suspension to obtain wood fiber/nano-crystalline cellulose aero-gel, performing crosslinking reaction of wood fiber/nano-crystalline cellulose aero-gel at 150-250 degrees C, preferably 160-180 degrees C, adding polyaniline to aerogel, after crosslinking, filtering, washing and drying the aerogel, and injecting carboxylated carbon nano tube and/or oxidation graphene dispersion liquid into aerogel, and filtering, washing and drying to form positively charged and negatively charged polyaniline carboxylase glycosylated carbon nanotubes and/or graphene oxide on wood fiber/nano crystalline cellulose aerogel, and repeating the steps to obtain wood fiber/nano-crystalline cellulose/(polyaniline-carbon nanotube) aerogel electrode material, wood fiber/nano-crystalline cellulose/(polyaniline-graphene oxide) aerogel electrode material or wood fiber/nanofiber crystal/(polyaniline-carbon nanotube/graphene oxide) aerogel electrode material.
