Novel route to polyaniline nanofibers from miniemulsion polymerization

A new synthesis approach for polyaniline (PANI) nanofibers with a yield of 95% was developed by using miniemulsion polymerization method. The nanofibers of 40 nm in diameter and 300 nm in length obtained had self-assembled to form a continuous conducting network, which induced a high conductivity of 1.23 S/cm. By investigating the morphologies and chemical structures of the PANI nanofiber by TEM, SEM, XRD, and FT-IR, a possible formation mechanism was proposed.
