| 中文摘要: |
| 采用水热法将聚丙烯酰胺(PAM)和十六烷基三甲基溴化铵(CTMAB)作为软性模板合成样品Ni(OH)2-PAM,Ni(OH)2-CTMAB和Ni(OH)2.在PAM和CTMAB的作用下,合成出来的样品有了更多的介孔,并且展现出了较宽的尺寸分布.通过扫描电镜(SEM)可以观察到不同的形貌.Ni(OH)2-PAM和Ni(OH)2-CTMAB基电极在1 A/g的放电密度下的比电容分别是1200 F/g和757 F/g,这大大地高于没加水溶性材料合成的Ni(OH)2样品基的电极的比电容,只有113 F/g.因此,适当的添加一些水溶性材料能够提高电极材料的电化学性能. |
| 英文摘要: |
| Poly(acrylamide) (PAM) and cetyltrimethylammonium bromide (CTMAB) were added as soft templates to synthesize nickel hydroxide (Ni(OH)2-PAM,Ni(OH)2-CTMAB,Ni(OH)2) via hydrothermal method.Different morphological characterization were compared by SEM.At the current density of 1A/g,the specific capacitances of Ni(OH)2-PAM,Ni(OH)2-CTMAB are 1200 F/g and 757 F/g,respectively,which both display a remarkably higher specific capacitance compared to Ni(OH)2,whose special capacitance is only 113F/g.The result reveals that water soluble polymers affect the pore size,and then contribute much to the capacitance. |
