We demonstrated here the lyotropic liquid crystalline behavior of an aqueous solution of graphene oxide (GO) sheets. Scanning electron microscope experiments revealed GO sheets self-assembled into fiber-like or sheet-like structures at different concentrations under flow conditions. As a result, the solution viscosity decreased dramatically with increasing shear stress.
我们在这里展示了氧化石墨烯（GO）片水溶液的溶致液晶行为。扫描电子显微镜实验表明，在不同浓度下，GO 片在流动条件下自组装成纤维状或片状结构。结果，溶液的粘度随着剪切应力的增加而急剧下降。
