窒化ホウ素ナノベルトエアロゲル及びその製造方法

Japanese Patent JP7197221

B2

The present application discloses a flexible boron nitride nanoribbon aerogel and a preparation method thereof. The flexible boron nitride nanoribbon aerogel has a 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 comprises: 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 of the present application has excellent flexibility and resilience, can withstand different forms of loads from the outside within a wide temperature range and has resilience. Furthermore, the preparation method is simple in preparation process, mild in reaction conditions, easy to operate, low in cost, green and free of pollution, and is capable of realizing continuous production.
