摘要： 碳纳米管具有良好的导电性和合适的双电层形成区，适于制作双电层电容器极板． 不同粘结剂的使用会影响电容器的性能，分别选用酚醛树脂和聚四氟乙烯（ＰＴＦＥ）作为碳纳米 管极板的粘结剂，在有机电解质溶液中，研究其电容性能与比表面积和极板结构的关系，从而 找出合适的碳纳米管极板粘结剂．

Abstract: Carbon nanotubes(CNTs) are suitable to make electrodes for electric double-layer capacitors(EDLCs),
because they possess excellent conductivity and suitable surface to form electric double layer. The properties of capacitors are influenced by
binders in electrodes. In our work, phenolic resin and teflon(PTFE) were chosen as binders to carbon nanotubes electrodes. Based on organic electrolyte, the relationship of capacitance property, specific surface and microstructure was studied, and the suitable binder (PTFE)
for carbon nanotubes electrodes was proposed.

Key words: electric double-layer capacitors(EDLCs), binder, carbon nanotubes(CNTs), organic electrolyte
