Abstract :
ZnO nanowire arrays on polyethylene terephthalate substrate were characterized, in terms of surface energy, by the honeycomb structured plasma jets for biosensors. A rapid hydrothermal synthesis is carried out to grow ZnO nanowires by a variable power microwave sintering system. The optical emission spectra of the honeycomb structured plasma jet array show that excited OH, N2, N2+, He, and O exist in the plasma jet array and the many gaseous species in the air participated in the plasma process. Surface modification by atmospheric plasma resulted in reduced contact angles from 111.23° to 8.70° as a function of plasma duration time.
