NOVELTY - Preparing open-pore foam/graphene oxide aerogel composite adsorbing material involves mixing solid powder of chitosan into 1 vol.% acetic acid solution, stirring mechanically, separating by centrifugation, and then dissolving oxidized graphene into de-ionized water, dispersing ultrasonically for 30 minutes, adding crosslinking agent, placing into special container, injecting graphene oxide/chitosan solution into container after vacuum exhaust and filling liquid into open-cell foam, taking graphene oxide/chitosan solution from container, transferring to oven and heating for multiple hours to form gelatinized foam/hydrogel, immersing in cooling medium of heat conducting plate, transferring to freeze drier to obtain foam/gel composite material, removing foam/gel composite material from freeze drier and placing in oven at 90 degrees C. USE - Method for preparing open-pore foam/graphene oxide aerogel composite adsorbing material. ADVANTAGE - The method enables to prepare open-pore foam/graphene oxide aerogel composite adsorbing material has low density, high specific surface area, high adsorption capacity characteristics and excellent foam mechanical properties.
