▎ 摘　　要

NOVELTY - Multifunctional wave-absorbing aerogel comprises graphene aerogel host and bridged polysilsesquioxane aerogel guest grown in the graphene aerogel host, where the mass ratio of the bridged polysilsesquioxane aerogel in the multifunctional wave absorbing aerogel is 90-96 wt.%. USE - The multifunction wave-absorbing aerogel is useful in wear-resistantelectronic device, national defense stealth technology, energy source, catalysis, and environment and electromagnetic shielding/absorption. ADVANTAGE - The aerogel: has high-strength, high-elasticity, and thermal insulation property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing multifunctional wave-absorbing aerogel comprising (i) dispersing graphene oxide and reducing agent in water to obtain a dispersion, chemically reducing graphene oxide hydrogel, aging and freeze-drying to obtain graphene aerogel, and (ii) mixing terephthalaldehyde, aminosilane, organosiloxane, acetic acid, ethanol and deionized water to form a mixed solution, immersing graphene aerogel body in the mixed solution by the dipping method, performing gelation to obtain graphene-bridged polysilsesquioxane wet gel, drying graphene-bridged polysilsesquioxane aerogel to obtain multifunctional wave-absorbing aerogel.
