▎ 摘  要

NOVELTY - Preparing super-hydrophobic sponge involves adding 0.05-0.3 pts. wt. oxidized graphene that is ultrasonically dispersed in 100 pts. wt. water. The obtained mixture is added with 1.5-10 pts. wt. hydrogen bromide. The obtained mixture is stirred at normal temperature. The obtained stirred mixture is added with 3-20 pts. wt. thiourea and 4-20 pts. wt. sodium hydroxide. The obtained mixture is stirred at 70-90 degrees C for 12-20 hours. USE - Method for preparing super-hydrophobic sponge used for oil-water separation application (claimed). ADVANTAGE - The method enables to prepare super-hydrophobic sponge with high selectivity and strong adsorption capacity. DETAILED DESCRIPTION - Preparing super-hydrophobic sponge involves adding 0.05-0.3 pts. wt. oxidized graphene that is ultrasonically dispersed in 100 pts. wt. water. The obtained mixture is added with 1.5-10 pts. wt. hydrogen bromide. The obtained mixture is stirred at normal temperature. The obtained stirred mixture is added with 3-20 pts. wt. thiourea and 4-20 pts. wt. sodium hydroxide. The obtained mixture is stirred at 70-90 degrees C for 12-20 hours. The obtained mixture is cooled to room temperature. The obtained mixture is filtered, and then washed with deionized water and ethanol. The obtained mixture is dispersed in mercapto ethanol ultrasonically. The obtained mixture is taken out, and then dried.
