NOVELTY - Preparing ultra-hydrophilic graphene involves orderly adding the organic amine solution and the reducing agent into the graphene dispersion liquid, ultrasonically stirring uniformly to obtain the mixed oxide dispersion graphene, adding hydrophilic polymer, ultrasonic stirring and dissolving in the mixed oxide dispersion graphene, obtaining uniform modified oxidation dispersion graphene, pouring the modified oxidized dispersion graphene into the mould, transferring into hydrothermal reaction kettle setting the temperature at 100-140degrees Celsius, reacting for 12-16 hours and then putting in refrigerator pre-freezing, vacuum freezing dry the porous graphene oxide aerogel, soaking porous reduced graphene oxide aerogel in the mixed solution prepared by inorganic alkali and organic alcohol, placing in an oven, setting the temperature at 60-100degrees Celsius, after 6-10 hours of deacetylation reaction and vacuum freezing, dry obtaining the ultra-hydrophilic graphene for desalting sea water gel. USE - Method for preparing ultra-hydrophilic graphene for super-hydrophilic sea water gel. ADVANTAGE - The method enables to prepare ultra-hydrophilic graphene that has super hydrophilic property, high elasticity, structure stability, long service life, it can effectively reduce the seawater desalination cost and improve seawater desalination efficiency, it has good application prospect in the sea water desalination.
