Synthesis and characterization of polyaniline microfibers by utilizing H4SiW12O40/polyacrylamide microfibers seeding template method

In this paper, polyaniline (PANI) microfibers with average diameter of 250 nm were synthesized by utilizing H4SiW12O40/polyacrylamide (HPA/PAM) microfibers seeding template method. The PANI microfibers were characterized by element analyses, FT–IR spectra, X-ray diffraction pattern (XRD), and Scanning electron micrograph (SEM). The microfibers seeding template significantly affected the fibrous morphology of the resulting PANI. However, the diameter of the PANI microfibers was almost not affected by the diameter of the microfibers seeding template in the experimental range. In addition, the conductivity of the PANI microfibers was also investigated. The result showed that the best conductivity of the PANI microfibers doped with H4SiW12O40 was 27.1 S/cm.
