Abstract :
Summary form only given. Characterization of highly stretchable and highly conducting polyacetylene films synthesized by two kinds of solvent-free polymerization procedures, called Solvent Evacuation and Intrinsic Non-Solvent methods, have been performed with respect to the solid state properties and thermal isomerization behavior, by means of X-ray diffraction (XRD), scanning electron micrograph (SEM), and differential scanning calorimetry (DSC). We present here a deeper insight into the overall relationships between stretchability, crystallinity, and film thickness, and also a new aspect on the stepwise cis-trans isomerization mechanism. Morphological comparison has also been made by addressing traditional S-type polyacetylene films.
