Expanded conformation of macromolecular chain in polyaniline with one-dimensional nanostructure prepared by interfacial polymerization

In this letter, the authors report the formation mechanism of one-dimensional nanostructural polyaniline prepared by an interfacial polymerization. The transmission electron microscopy image of the conducting polymer exhibits a diameter of ∼80nm and a length of ∼1μm. The resistivity of the polymer at room temperature is 3.03±0.05Ωcm. The measurement of in situ UV-visible spectra showed an “expanded and partly doped” stage in the interfacial polymerization. It is hypothesized that the expanded molecular conformation performs a molecular template function on the formation of one-dimensional structure in the synthesis process.
