摘要：

Small-angle X-ray scattering data obtained from drawn films of the emeraldine base form of polyaniline indicate the development of an array of crystalline regions which is periodic along the draw axis. The spacing is 16 +/- 3 nm and the extent of the crystallites is about 6 nm. Doping the films with Cl- appears to reduce the electron density of the crystalline regions and eliminates this source of scattering.
