摘要：

An experimental study of a plasma plume generated by radio frequency atmospheric pressure glow discharge and enhanced in terms of plume length and intensity by pulsed discharge is presented. When injecting a pulsed plasma bullet into the radio frequency plasma plume, the length of the plasma plume into ambient air can be elongated from 2 mm to 6 mm and the intensity of the plasma plume can be elevated by four times. The propagation of the pulsed plasma bullet and the interaction with radio frequency discharge and plume are demonstrated by the temporal evolution of the discharge spatial appearance. The enhanced plasma plume is employed to improve the O/C ratio of carbon fiber, which is attributed to the synergistic effect of the radio frequency plasma plume and pulsed plasma bullet.
