Using a high voltage (0-20kV) power supply operating at 10-30kHz, homogeneous and steady APGD has been observed between the electrodes with gap spacing from 0.5mm to 2mm and with a dielectric barrier of thickness 2mm while argon gas is fed at a controlled flow rate of 1l/min. The electron temperature and electron density of the plasma are determined by means of optical emission spectroscopy. Our results show that the electron density of the discharge obtained is of the order of 1016cm − 3 while the electron temperature is estimated to be 0.65eV. The important result is that electron density determined from the line intensity ratio method and stark broadening method are in very good agreement. The Lissajous figure is used to estimate the energy deposited to the glow discharge. It is found that the energy deposited to the discharge is in the range of 20 to 25μJ with a discharge voltage of 1.85kV. The energy deposited to the discharge is observed to be higher at smaller gas spacing. The glow discharge plasma is tested to be effective in reducing the hydrophobicity of polyethylene film significantly.
