Fig. 5 SEM images and EDAX results for the PAn-Pd composite
on this fact, we can conclude that palladium particles are incorporated directly into
the polymer matrix. In this case, the granulometric analysis failed due to the difficulty
of setting the boundaries of individual objects.
On the example of PAn-Ag composites, we traced the influence of metal content on
the structural features of the obtained materials. The surface morphology of composites with low silver content (2.5 wt%) is rather uneven and has the appearance of
pyramidal structures similar to polymer crystals up to 150 nm in height (see Fig. 6).
