TL;DR: In this paper, a core-shell polypyrrole/polyaniline (PPy/PANI) composite was prepared by in situ chemical oxidation polymerization of aniline on the surface of PPy nanotubes.

TL;DR: In this paper, the template and oxidant played important roles in the formation of PANI nanofibers, and the PANI electrode exhibited high discharge/charge efficiency of 93% and the capacitance retention of 83% at a current density of 5.1 µm−2, indicating good electrochemical reversibility and rate capability.

TL;DR: In this article, a core-shell structure with PANI layers (50-70 nm) was shown to have a high specific capacitance of 322 F/g with a specific energy density of 22 W h/kg, about 12 times that of MWNTs.

TL;DR: In this paper, a mixture of 96% sulfuric acid and 4-aminobenzenesulfonic acid was used to produce intermediate diazonium salts from substituted anilines.

TL;DR: In this article, a hierarchical Ni-Co-P heterostructure assembled by porous nanoplates is achieved, which displays the metalloid property, multi-component synergy, high reaction activity, and rapid electron transfer/ion diffusion behavior.
