石墨烯-聚苯胺（GP）纳米复合材料作为超级电容材料已经显示出显著的能力，并且通常通过氧化石墨烯/聚苯胺（GOP）前体的化学还原来合成。我们报告形成新的纳米材料结合GOP纳米复合材料与Laponite纳米盘。GOP系统内的主客体相互作用进行了研究，有和没有Laponite纳米粒子模板剂。将锂皂石粘土掺入复合材料合成中增强了水性分散性，并促进了均匀膜的浇铸。结构和形态表征证实了多孔异质界面和聚合物和纳米粘土负载的控制。这些结果可以使柔性超级电容和太阳能纳米复合材料的开发具有改进的设备实用性、水稳定性和膜可加工性。我们证明，这些薄膜可以很容易地铸造和复合材料保持其电传输性能。
Graphene-polyaniline (GP) nanocomposites have demonstrated remarkable ability as supercapacitive materials and are typically synthesized via chemical reduction of graphene oxide/polyaniline (GOP) precursors. We report the formation of novel nanomaterials combining GOP nanocomposites with Laponite nanodisks. Host-guest interactions within GOP systems were studied with and without Laponite nanoparticle templating agents. Incorporating Laponite clay into the composite synthesis enhances aqueous dispersibility as well as facilitates the casting of homogeneous films. Structural and morphological characterization confirmed porous heterointerfaces and control of polymer and nanoclay loading. These results may enable the development of flexible supercapacitive and solar nanocomposites with improved device utility, water dispersibility, and film processability. We demonstrate that these films can be easily cast and that the composites maintain their electrical transport properties.
