| Summary: | The peculiarities of the structure of polymers synthesized in a low-pressure glow discharge in vapors of adamantane on the electrodes and substrates at a “floating” potential are described. The structure of the product formed is conditioned by the ratio of deposits of the mechanisms of the surface and volume polymerization in the formation of the polymer on the surface. The determining factors are the type of discharge and its parameters — direct or alternating current discharge, pressure and current density, presence of the flow of gas or its absence in connection with the feed in the zone of formation of coatings and set out from her particles of the dispersed phase; the location of the substrate in the area of the discharge and outside of it. The kinetics of growth of films of adamantane at different discharge conditions on the electrodes of different materials — aluminum and copper was studied. The growth rate of polymers varied between 0.5–1.4 nm/s at the anode, and 4.2–7.5 nm/s at the cathode for different discharge modes and two electrode materials. |
