Abstract:
A novel, highly efficient and economical route is
developed for the synthesis of polyaniline micro-/nanostructure. Materials were characterized by a complementary
combination of X-ray diffraction, Scanning electron microscopy, Fourier-transform infrared, and UV-visible spectrophotometer. Morphology of polyaniline can be tailored by varying
the structure-directing agents and pH of the synthesis
condition. Ethylene glycol and polyethylene glycol formed a
three-dimensional flower-like structure whereas blockcopolymer (ethylene oxide and propylene oxide based copolymer EO20PO70EO20) formed leaf-like structure when the
synthesis was performed at pH 7. Using these structuredirecting agents, nanorod and granular morphologies were
obtained when the samples were synthesized at pH 3 and 1,
respectively.
