NOVELTY - Preparing bamboo fiber and graphene oxide composite aerogel comprises (S1) soaking the bamboo fiber in the graphene oxide liquid, adding cosolvent, then homogenizing at 12000 revolutions/minute by high shear homogenizing stirrer for 1 hour, crushing the bamboo fiber to obtain cut nano- fiber, and forming uniform bamboo nano fiber dispersion liquid, (S2) pouring the nano fiber dispersion into the mold for freezing at -20degrees Celsius for 6 hours, and keeping in the vacuum drying environment for 48 hours, and (S3) sintering the dried primary aerogel at a certain temperature for 30 minutes to obtain the bamboo fiber graphene oxide composite aerogel. USE - The method is useful for preparing bamboo fiber and graphene oxide composite aerogel. ADVANTAGE - The method: is simple and convenient; adopts low-cost bamboo fiber; and utilizes the stable pore structure of the bamboo fiber itself, which can efficiently improve the pore structure of the aerogel. The aerogel has a better filtering effect and a good application prospect.
