Formation of structured coatings based on carbon and polyacrylamide, influence of thermal treatment on their phase composition and morphology

The morphological features of two-layer coatings based on polyacrylamide and carbon, formed in a single technological cycle by electron beam and cathode-pulse methods, respectively, are considered. The effect of heat treatment in air on the morphology, phase composition, and structural transformations in such two-layer systems is established. It was shown that heat treatment of a polyacrylamide layer in air (300$^\circ$ С, 60 minutes) leads to the complete disappearance of nitrile groups, which may be a consequence of cyclization.
