Plasma Polymerization of Acrylic Acid Revisited

To perform a systematic study over a broad parameter range of acrylic acid discharges, we varied the energy input W / F over a wide range. Five different regimes could be identified (from low to high energy input): regime I, where oligomerization takes place; regime II, the radical‐dominated plasma polymerization of acrylic acid; regime III, a transition regime showing etching/oxidation effects; regime IV, where the plasma polymerization...
