聚苯胺-石墨烯-Co3O4纳米复合材料的制备及其表征

摘要

首次以三步法制备了聚苯胺-石墨烯-Co3O4(PANI-RGO-Co3O4)纳米复合材料.利用FT-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CoO4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.%The polyaniline-reduced graphene oxide-Co3O4 (PANI-RGO-Co3O4) nanocomposites were synthesized through a three-step approach for the first time.The nanocomposites 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 Co3O4nanoparticles,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.
