Oligomer-assisted synthesis of chiral polyaniline nanofibers.

摘要: We report here a novel approach to synthesize chiral PANI nanofibers in an aqueous solution. This new requires the following conditions:  (1) Polymerization was carried out concentrated camphor sulfonic acid solutions. (2) Aniline oligomers were used accelerate polymerization reaction. (3) Ammonium persulfate (oxidant) added incrementally aniline The high anisotropy factor of these is likely due “autocatalytic effect” resulting from lower oxidation potentials oligomers. Our chemical synthesis enantioselective and, under optimized conditions, has (g = Δe/e) 2.3 × 10-2.
