Nanotubular polypyrrole: Reversibility of protonation/deprotonation cycles and long-term stability

[Display omitted] •Alteration of conductivity by deprotonation/reprotonation is a reversible process.•Deprotonation proceeds even at very low concentration of alkali.•The absolute values of conductivity are given by the age of reprotonated samples.•Deprotonation of polypyrrole nanotubes decreases th...
