A portable dielectric barrier discharge device operated under one atmosphere is developed and the use of this device for surface treatment is performed. This device consists of a powered electrode made of a copper plate, a ground electrode made of stainless steel woven wire mesh, and a quartz plate 1 mm in thickness that serves as dielectric barrier between powered and ground electrode. This device is driven by a portable power source that is commercially available. This power source supplies voltages up to 20 kV with a frequency of 20-50 kHz. This plasma system is compact and low cost. Surface treatment under air, argon, and nitrogen atmosphere on PET, glass, and PTFE substrates to enhance hydrophilicity is performed. It is found that the water contact angle of the glass surface decreases from 40° to below 10° after treated using this device for 5 min operated in air and argon. For PET surface treatment under argon atmosphere, the contact angle decreases from 70° to 20° after 5 min of treatment. Due to its low cost and compact size, this portable DBD device shows great potential in various applications where portable devices are desired.
