Polyaniline nanopaticles for supercapacitor were prepared by using polystyrene microsphere as carrier. They were characterized by FTIR, SEM and TGA for structure and electrochemical station for supercapacitive performance. The results show that, the polystyrene-polyaniline composite, about 4∼5 µm, keep the microsphere structure of polystyrene, and was covered on its surface with polyaniline nanoparticle...
A novel nano-composite of polyaniline/mesoporous carbon (PANI/CMK-3) was prepared with mesoporous carbon (CMK-3) serving as the support. Electrochemical asymmetric capacitors have been successfully designed by using PANI/CMK-3 composite and CMK-3 as positive and negative electrode, respectively. The results showed that the discharge capacity of the asymmetric capacitor could reach 87.4F/g under the...
Multi-walled carbon nanotube (MWCNT)/polyaniline (PANI) composite films were prepared by in-situ electrochemical polymerization of an aniline solution containing different MWCNT contents. The supercapacitive behaviors of these films were investigated with cyclic voltammetry (CV), charge–discharge tests, and ac impedance spectroscopy. The results revealed that the MWCNT/PANI films show much higher...
