Summary:In this paper, the results of wettability improvement of Mylar substrate are presented. The experimental work is done with an atmospheric-pressure nonthermal plasma jet, ANPJ device. This device is energized by a low-cost Neon power supply of (10 kV, 30 mA, and 20 kHz). It is operated separately with N2 gas and compressed air at a flow rate of 12 L/min for each of them and input voltage of 6 kV. A Mylar substrate is treated using both carrier gases. The wettability of Mylar substrate is measured using contact angle technique. The contact angle is detected using two techniques: spherical cap approach and Low-bond axisymmetric drop shape analysis. The results show wettability improvement of this substrate surface for both carrier gases but the N2 plasma jet is more effective than Air plasma jet.
