This work reports porous bulks assembled from highly crystalline and uniform polyaniline (PANI) nanofibers via reverse microemulsion polymerization. PANI nanofibers have a very narrow diameter of 15 similar to 25 nm and a length of 100 similar to 200 nm. The electrochemical tests reveal that PANI nanofibers have high specific capacitance of 493 F g(-1) a current density of 0.5 A g(-1). With the increase of the current from 0.5 up to 2 A g(-1), PANI still retains more than 80% of initial specific capacitance, implying good rate capability. The good capacitive performance benefited from the porous structure of conductive PANI demonstrates its potential in electrochemical devices.
