摘要
Polyaniline(PANI)was effectively immobilized on the surface of ordered mesoporous carbon(OMC)by using Mn_2O_3 as sacrificial template.The observed microstructure and morphology indicate that a thin layer of PANI was coated on OMC uniformly.As a supercapacitor electrode material,the discharge capacity of the optimized PANI/OMC could reach 467 F/g,which is far higher than that of OMC,PANI and Mn_2O_3/OMC.Furthermore,PANI/OMC composites with different content of PANI are obtained by adjusting the amount of Mn_2O_3 on OMC and their properties are characterized.The results show that a thin layer of PANI can improve the capacity of PANI/OMC composites effectively and the further increase of PANI reduces the capacity of PANI/OMC composites.The sacrificial template method presented here is beneficial to coating a layer of polymer on carbon materials,and the content of polymer layer can be controlled by adjusting the amount of Mn_2O_3 in Mn_2O_3/OMC.
Polyaniline （PANI） was effectively immobilized on the surface of ordered mesoporous carbon （OMC） by using Mn2O3 as sacrificia l template. The observed microstructure and morphology indicate that a thin layer of PANI was coated on OMC uniformly. As a supercapacitor electrode material,the discharge capacity of the optimized PANI/OMC could reach 467 F/g,which is far higher than that of OMC, PANI and Mn2O3 /OMC. Furthermore, PANI/OMC composites with different content of PANI are obtained by adjusting the amount of Mn2O3 on OMC and their properties are characterized. The results show that a thin layer of PANI can improve the capacity of PANI/OMC composites effectively and the further increase of PANI reduces the capacity of PANI/OMC composites. The sacrificial template method presented here is beneficial to coating a layer of polymer on carbon materials, and the content of polymer layercan be controlled by adjusting the amount of Mn2O3 in Mn2O3 /OMC.
