A series of alkyl chain modified graphene oxides (AmGO) with different alkyl chain length and content was fabricated using a reducing reaction between graphene oxide (GO) and alkyl amine. Then AmGO was used as a graphene-based particle emulsifier to stabilize Pickering emulsion. Compared with the emulsion stabilized by GO, which was oil-in-water type, all the emulsions stabilized by AmGO were water-in-oil type. The effects of alkyl chain length and alkyl chain content on the emulsion properties of AmGO were investigated. The emulsions stabilized by AmGO showed good stability within a wide range of pH (from pH = 1 to pH = 13) and salt concentrations (from 0.1 to 1000 mM). In addition, the application of water-in-oil emulsions stabilized by AmGO was investigated. AmGO/polyaniline nanocomposite (AmGO/PANi) was prepared through an emulsion approach, and its supercapacitor performance was investigated. This research broadens the application of AmGO as a water-in-oil type emulsion stabilizer and in preparing graphene-based functional materials.
通过氧化石墨烯（GO）与烷基胺之间的还原反应制备了一系列具有不同烷基链长度和含量的烷基链修饰氧化石墨烯（AmGO）。然后将AmGO用作基于石墨烯的颗粒乳化剂来稳定皮克林乳液。与由GO稳定的水包油型乳液相比，所有由AmGO稳定的乳液均为油包水型。研究了烷基链长度和烷基链含量对AmGO乳液性能的影响。由AmGO稳定的乳液在很宽的pH范围（从pH = 1到pH = 13）和盐浓度范围（从0.1到1000 mM）内均表现出良好的稳定性。此外，还研究了由AmGO稳定的油包水乳液的应用。通过乳液法制备了AmGO/聚苯胺纳米复合材料（AmGO/PANi），并研究了其超级电容器性能。本研究拓宽了AmGO作为油包水型乳液稳定剂以及在制备基于石墨烯的功能材料方面的应用。
