Plasma-induced polymerization



Low vapor tension polymerized acrylates as thin films when they are subjected to a cold plasma. The plasma-induced polymerization is described in terms of direct or indirect energy transfer from the plasma to the monomer. The indirect transfer is related to the absorption of UV-visible radiations by the monomer. The radiations are emitted from excited species of the plasma. Direct transfers correspond to the reactive species collision (radicals, ions metastable species) with a molecule of monomer. The polymerization is a result of these two kinds of transfers. Direct transfers lead to competitive reactions (addition, terminations and degradation, etc.) and acrylate polymerization is mostly induced by the UV-visible radiations.
