通过氧化石墨烯（GO）片的表面电荷密度放大的尺寸分级拓宽了氧化石墨烯（GO）的水性分散体中的pH依赖性各向同性（I）至均质（N）相变。在该两相区中，观察到具有均匀尺寸（20 ± 2.8 μm直径）和各向同性内部的高度组织化的液滴中间相。
Size fractionation, amplified by the surface charge density of graphene oxide (GO) sheets, broadens the pH dependent isotropic (I) to nematic (N) phase transition in aqueous dispersions of graphene oxide (GO). In this biphasic region, a highly organized droplet nematic phase of uniform size (20 ± 2.8 μm diameter) with an isotropic interior is observed.
