NOVELTY - Preparing organic modified vermiculite/graphene composite aerogel involves adding vermiculate nanosheet into aqueous solution contains modifying agent, and ultrasonically dispersing uniformly to obtain organic modified vermiculite dispersion liquid; adding oxidized graphite powder to organic-modified vermiculation dispersion solution, cutting and dispersing, adding reducing agent to adjust pH value of solution to obtain mixed dispersion of organic modified vermiculite and graphene oxide; carrying out two-step hydrothermal reaction to obtain organic modification vermiculation mixture, and washing organic modify vermiculation mixture with deionized water for 2-3 times, removing impurities, and freezing and drying to obtain final product. USE - Method for preparing organic modified vermiculite/graphene composite aerogel used in field of environment restoration. ADVANTAGE - The method enables to prepare organic modified vermiculite/graphene composite aerogel, which has high mechanical strength.
