| Popis: | Small angle X-ray scattering experiments on amorphous and partially crystalline samples of polyaniline stretched by two different methods indicate the development of quite different structural features in the size range 5–100 nm. A qualitative comparison of wide angle scattering data shows that both processing methods produce orientation at the molecular level. The two types of scattering experiments indicate that the stretching processes result in reduced crystallinity. Doping the stretched polymers with Cl− was found to produce changes in both large and small scale structure. |
