| Outline of Final Research Achievements |
For generation of highly reactive, non-equilibrium plasma at atmospheric pressure, plasma is generated by applying short pulse voltage at a high repetition frequency to a narrow-gap electrode system. The properties of the plasma such as the gas temperature and the electron impact excitation rates are diagnosed by the analysis of the optical emission and the discharge voltage and current waveforms. In addition, the advantage of the plasma is discussed when the plasma is used for surface oxidation of polyethylene terephthalate (PET).
From the results of plasma diagnostics, the plasma is found to be in non-equilibrium. Thus, it is confirmed that the highly reactive conditions of the plasma is realizable. The surfaces of PET films are oxidized clearly when the films are exposed to the plasma for a net time shorter than 0.1 s. These results indicate that the plasma proposed in this study are promising in the applications to polymer surface treatments.
