摘要
Ultralightweight (specific gravity 5 X 10(-2)) and highly conductive (2.5 S/cm) monolithic carbon aerogels exhibiting a three-dimensionally continuous micro- and macroporous structure have been prepared through a PPO-PEO-PPO block copolymer assisted route. The resulting carbon aerogels were highly suitable as electrodes of electric double layer capacitors, with remarkable values of capacitance of up to 225 F/g (normalized by mass) and 31 mu F/cm(2) (normalized by BET surface area).
