Localized Electric Field Roles in Nonthermal Corona Plasma for Surface Functionalization

We present the primary roles of Localized a nonuniform electric field in Nonthermal Corona Plasma inducing electrochemical reactions on biological surfaces. The combining structure of the corona and dielectric barrier were employed as a hybrid structure to induce the localized electric field up to 10
⁶
V/cm around the electrode edge, leading to a partial breakdown of air and initiating the cold plasma process. We performed cold plasma treatment on rice seed under two different ambient (air and air-Ar) on rice seed to observe the relative correlation of water imbibition at several treatment time windows. The results indicate that the reactive species generation in the plasma region will be directly related to electron emission but indirectly the surface functionalization.
