| Description | This work aimed to enhance the surface properties of SentryGlas (SG) ionoplast for laminated safety glass using two nitrogen-based atmospheric pressure plasma sources: a commercial plasma curtain (ULD 60) and a novel linear atmospheric pressure plasma jet (APPJ) based on Diffuse Coplanar Surface Barrier Discharge (DCSBD) technology (DCSBD linear APPJ). The wettability and adhesion properties were evaluated through the water contact angle (WCA) and adhesion measurement. Surface chemistry was investigated by XPS and the morphology changes by SEM measurements. WCA results demonstrated that both plasma sources significantly improved the wettability of the SG ionoplast, with the ULD 60 exhibiting slightly superior performance. However, the DCSBD linear APPJ plasma treatment resulted in better stability and a slower ageing effect. XPS analysis showed that more oxygen-enriched or nitrogen-enriched functional groups were introduced onto the SG ionoplast surface after plasma treatment. SEM observations indicated that the ULD 60 induced notable morphological changes on the surface at a smaller treatment distance (10 mm and 30 mm), whereas the DCSBD linear APPJ did not induce any obvious morphological changes within the range of 10–80 mm. Adhesion measurements confirmed that both plasma treatments significantly improved the adhesion properties of the SG ionoplast. |
