Plasma treatment is an effective surface activation technique valued for its spatial precision. Atmospheric pressure plasma-jet printer (PJP) has a dielectric barrier discharge plasma which can be utilized for simultaneous surface activation and deposition of nanoparticles. In this study, we employ a PJP printer to tailor surface hydrophilicity, improve adhesive bonding, and deposit self-sintered patterned metal traces. Here, we conduct a systematic investigation exploring the impact of plasma parameters (voltage, gas flow, working distance) on surface energy and wettability. Optimal treatment conditions were established, which is utilized to the enhance the adhesion of nanoparticles onto the modified surfaces. This work demonstrates PJP's potential for in-situ and simultaneous surface modification, self-sintering, and improved adhesion, offering tailored functionality for diverse applications.
