A flexible boron nitride nanoribbon aerogel has an interconnected three-dimensional porous network structure which is formed by mutually twining and contacting boron nitride nanoribbons and consists of macropores having a pore diameter of more than 50 nm, mesopores having a pore diameter of 2-50 nm and micropores having a pore diameter of less than 2 nm. The preparation method of the flexible boron nitride nanoribbon aerogel includes the following steps: performing high-temperature dissolution on boric acid and a nitrogen-containing precursor to form a transparent precursor solution, preparing the transparent precursor solution into precursor hydrogel, subsequently drying and performing high-temperature pyrolysis to obtain the flexible boron nitride nanoribbon aerogel. The boron nitride nanoribbon aerogel has excellent flexibility and resilience and can withstand different forms of loads from the outside within a wide temperature range.
