| Atmospheric pressure weakly ionized plasma (APWIP) is being used to treat or process goods and materials because it only activates the surface without modification of the bulk material. This work describes research into the synchronicity of corona discharges and some applications of APWIP. A reactor was built to generate corona discharges using an array of needles, the geometry of each needle being consistent with point-to-plane configuration. The interaction between corona discharges in the needle array was studied. The reactor was then used to decontaminate fresh produce inoculated with E. coli ATCC 1177 and to deposit films via plasma polymerization of acetylene. |
