摘　　要：为提高Cu(OH)2泡沫铜的油水分离能力,将泡沫铜浸入正十二烷基硫醇(NDM)制得NDM/Cu(OH)2油水分离膜,经过NDM修饰后的泡沫铜实现了连续高效捕获微米级油滴的目的。研究结果表明:油水分离膜具有大约150μm孔径的Cu(OH)2孔状结构;相比未修饰油水分离膜,NDM修饰的油水分离膜的分离效果明显增加,均达95%以上。该研究有助于提高油水分离效果,为后续的应用测试奠定一定的理论基础。In order to improve the oil-water separation ability of Cu(OH)2 foam,N-dodecyl mercaptan(NDM)/Cu(OH)2 oil-water separation membrane was prepared by dipping Cu(OH)2 foam into NDM.The NDM modified copper foam achieves the purpose of continuous and efficient capture of micron oil droplets.Researches result show that the oil-water separation membrane has a density of about 150μm Cu(OH)2 porous structure.Compared with the unmodified oil-water separation membrane,the separation effect of NDM modified oil-water separation membrane is significantly increased,reaching more than 95%.This study is helpful to improve the separation effect of oil and water,and lays a theoretical foundation for the subsequent application test.
