摘　　要：为改善油水分离性能,采用共沉淀法制备了ZIF-8/氧化石墨烯/聚氨酯(ZIF-8/GO/PU)复合海绵。通过X射线衍射仪、扫描电子显微镜和能谱仪对其进行表征,结果表明:ZIF-8/GO与海绵基底复合,复合海绵的疏水性以及亲油性都明显提高,其纯水通量最高可达1.01L/(cm^(2)·s),纯油吸附能力达39.43g/g,并且经过20次吸脱附循环后仅下降7.8%。In order to improve the oil-water separation performance,ZIF-8/graphene oxide/polyurethane(ZIF-8/GO/PU)composite sponge was prepared by co-precipitation method.It was characterized by X-ray diffractometer,scanning electron microscope and energy spectrum.The results showed that ZIF-8/GO was successfully combined with sponge substrate.The hydrophobicity and lipophilicity of the composite sponge were significantly improved.The pure water flux of the composite sponge was up to 1.01L/(cm^(2)·s).The pure oil adsorption capacity of the composite sponge reached 39.43g/g,and only decreased by 7.8%after 20 cycles of adsorption and desorption.
