Polyimides are widely used in industry because of their excellent resistance in heat and very good mechanical properties. Electrically conductive polyimide composites are under focus of the research for application in electronics, aircraft and automobile industry. To prepare electrically conductive polyimides we used conjugated polymer: polypyrrole. The presence of conjugated double bonds in the composite reunited in intermolecular complexes with charge transfer. The presence of polypyrrole also affected an imidization temperature; the temperature of poly(amic acid) conversion to polyimide. In this paper imidization of poly(amic acid) was investigated by Fourier transform infrared spectroscopy, and differential scanning calorimetry. Morphological changes in polypyrrole/polyimide composite were studied by scanning electron microscopy. Results were explained by conformational changes in poly(amic acid) under the influence of polypyrrole.
