Stabilizer-free conducting polyaniline nanofiber aqueous colloids and their stability

Stabilizer-free polyaniline nanofiber aqueous colloids were obtained by the direct dispersing of polyaniline nanofiber prepared in the presence of β-cyclodextrin. The polyaniline nanofiber, the diameters of which are between 80 and 100 nm, can be steadily dispersed in near neuter (pH = 6.5) aqueous solution for about 60 days without any steric or electrostatic stabilizer.
