▎ 摘  要

NOVELTY - Preparing aerogel foam with silencing function comprises (S1) mixing the MXene dispersion and the graphene oxide dispersion to form a mixed dispersion, (S2) freeze-drying the mixed dispersion to obtain MXene-doped graphene oxide, and (S3) subjecting the MXene-doped graphene oxide to a reduction reaction to obtain the aerogel foam with a silencing function. USE - The method is useful for preparing aerogel foam with silencing function, which is used in tires. ADVANTAGE - The method provides graphene aerogel gel foam with good flexibility and three-dimensional continuous porous network structure. The material: has a good absorption effect on cavity noise; can significantly reduce tire noise; improves passenger comfort; and reduces noise pollution to the environment. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: a tire comprising an inner liner, where the inner surface of the inner liner is adhered with the aerogel foam with silencing function. (1) an aerogel foam with silencing function; and
