摘要

The zone-drawing method was applied to chemically synthesized polyaniline cast films of emeraldine base under various applied tensions and drawing temperature . The changes in the microstructure and viscoelastic properties of the resultsing films were invstigated. It was found that the microstructure was strongly affected by the drawing temperature (T_d). The crystallinity, crystallite size, and orientation factor of crystallites, respectively, attained 42% 23A, and 0.975 for the film zone-drawn at T_d =170degC, whereas a further increase in the T_d brought about a decrease of these values. The viscoelastic measurements indicated that the dynamic storage modulus attained 12 GPa at room temperature and was 5 GPa at 280degC for the film zone-drawn at T_d =210degC, which was comparable to that of the typical engineering plastics.
