聚苯胺一石墨烯-Co3O4纳米复合材料的制备及其表征

首次以三步法制备了聚苯胺一石墨烯-Co3O4PANI—RGO-Co3O4纳米复合材料。利用F]＇-IR，XRD，XPS和TEM对所制备的纳米复合材料进行表征，结果表明：PANI—RGO-Co3O4纳米复合材料中氧化石墨（GO）的含氧官能团数量大幅降低，GO已被还原成石墨烯（RGO）；PANI和RGO之间具有较强的相互作用，且形成的-Co3O4纳米粒子分布在PANI—RGO表面，其粒径在5-15nm之间，该纳米复合材料有望在超级电容器材料、电极材料和吸波材料等领域有广泛的应用前景。

Preparation and Characterization of Polyaniline-Reduced Graphene Oxide-Co3O4 Nano-composites

The polyaniline-reduced graphene oxide-Co3O4 （PANI-RGO-Co3O4） nanocomposites were synthesized through a three-step approach for the first time. The nanoeomposites were characterized by FT-IR, XRD, XPS and TEM. The results indicated that the oxygen-containing functional groups of GO decreased to a great extent; the GO had been reduced into RGO. The PANI greatly interacted with RGO and the formed Co3O4 nanoparticles, with a particle size of 5-15 nm, were closely anchored on the surface of PANI-RGO. The nanocomposites were expected to have wide applications in super capacitor, electrode and wave-absorbing materials.
