Abstract

The invention discloses a device for improving adhesive property of a polyimide substrate exciter by low-temperature plasma. The device comprises a high-voltage DC power supply (101), a DC voltage power output end (102), an insulation handle (103), a first insulation body (104), a second insulation body (105), a third insulation body (106), a fourth insulation body (107), a fifth insulation body (108), a discharging positive electrode (109), a pulley (110), a negative electrode metal plate (111), a sliding way (112) and a plasma body discharging region (113). The invention also provides the special operation process of surface treatment of the exciter. The surface of the plasma exciter is subjected to effects of impact and modification of the plasma, the adhesive property of the exciter can be improved and enhanced, and the polyimide dielectric blocking discharging plasma exciter with favorable adhesive property is generated after repeated operation for many times. By the method, the adhesive property of the plasma exciter can be substantially improved.
