| 摘 要： | 利用界面扩散聚合法制得了樟脑磺酸掺杂聚苯胺纳米管或纳米纤维.扫描电镜(SEM )和透射电镜(TEM)表明所生成的聚苯胺纳米管径与樟脑磺酸浓度成反比,且低浓度的苯胺和掺杂剂有利于管状及纤维状聚苯胺的形成.充放电测试结果表明,聚苯胺纳米管在5mA放电时电容值可达2 4 9F g ,比相同条件下聚苯胺纳米纤维的比电容高14 . 7% ,而比聚苯胺粉末的比电容高4 1 .5 % .

| Abstract: | camphorsulfonic acid doped polyaniline (PANI-CSA) nano-tubes and nano-fibrils fa bricated by interfacial polymerization (IP) without templates.The SEM and TEM images revealed that the average diameter of obtained polymer nano- t ubes or nano-fibrils was about 100?nm.It is proved that the lower concentrat ion s of aniline and dopant were liable to the PANI-CSA nano-tube or nano-fibrils fo rmation.Furthermore,charging-discharging tests revealed the good electrochemic al capacitance performance of PANI-CSA nano-tubes.Their specific capacitance was as high as 249 F/g at 5?mA discharging compared to that of the fibrous PAN I-CSA (217 F/g at 5 mA) and the granular PANI-CSA (176 F/g at 5?mA). |
