A facile and versatile method for the synthesis of Janus graphene oxide (GO) nanosheets with different structures is reported. Based on electrostatic assembly, Janus GO nanosheets can be easily functionalized with a template polymer or be defunctionalized by altering the ionic strength. By using this approach, Janus GO nanosheets are prepared successfully with hydrophobic polystyrene chains on one side and hydrophilic poly(2-(dimethylamino)ethyl methacrylate) chains on the other side.
报道了一种简便通用的合成具有不同结构的氧化石墨烯（GO）纳米片的方法。基于静电组装，氧化石墨烯纳米片可以很容易地用模板聚合物进行功能化，或者通过改变离子强度来去除功能化。通过这种方法，成功制备了一侧带有疏水聚苯乙烯链而另一侧带有亲水聚（甲基丙烯酸2-（二甲氨基）乙酯）链的氧化石墨烯纳米片。
