Polyaniline microrods synthesized by a polyoxometalates/poly(vinyl alcohol) microfibers template

Polyaniline (PAn) microrods doped with H 4 SiW 12 O 40 (HPA) were obtained by a H 4 SiW 12 O 40 /Poly(vinyl alcohol) microfibers template method. The morphology of the polyaniline microrods was observed by scanning electron microscope (SEM) photograph. The average diameter of the polyaniline microrods was between 200 and 250 nm. IR spectra and X-ray diffraction characterized the structure of the polyaniline doped with H 4 SiW 12 O 40 . The conductivity of the polyaniline microrods was measured by a four-probe method. The highest conductivity of the polyaniline microrods was 3.9 S/cm.
