摘要(Abstract)：

采用一步法将不锈钢网进行酸刻蚀并吸附葡萄糖酸（GA），成功制备了超亲水-水下超疏油的葡萄糖酸改性不锈钢网（GAG-网）。采用扫描电子显微镜、X-射线光电子能谱仪对GAG-不锈钢网表面形貌和化学组分进行表征，结果表明GA成功地吸附在了不锈钢网上和网表面成功构造微纳米粗糙结构。采用接触角测量仪对其表面进行了润湿性测试，在空气中，水滴在其表面接触角为0°；在水下，油滴在其表面接触角大于150°。GAG-网能够有效地分离多种油水混合物，分离效率均达到98%以上，分离通量达140 L·（m²·s）^-1；分离正己烷/水的混合物40次后仍具有99.5%以上的分离效率；在腐蚀性环境中也具有优异的分离能力。该方法简单绿色，制备过程无需任何电器和机械设备。制备的GAG-网油水分离性能优异，在处理油水混合物方面具有潜在的应用前景。
