Emerging applications for functionalized and smart glass surfaces have created a market pull effect for scalable digital manufacturing processes in the glass industry. Precise lateral and thickness control in additive fluid deposition processes such as inkjet printing, spray coating and drop casting rely on tuning surface wettability to match with the fluid properties. Typical industrial approaches to modifying surface wettability involve air plasma treatment and deposition of self-assembled monolayers. If patterned control of wettability is needed, these are normally followed by lithographic approaches. Here, we explore direct-write femtosecond laser patterning and shadow-masked plasma treatment as alternative approaches for rapid pattern modification of glass surface structure and surface chemistry to control wettability. We also show the use of these techniques for local removal of functional surface coatings. These capabilities can be combined to enable the digital patterning of contrasting regions of hydrophilicity-hydrophobicity on glass surfaces. We demonstrate surface confinement of liquid drops and capillary-driven spreading. The underlying mechanism of wettability control is determined through combining high-speed imaging of liquid flow with surface chemistry mapping. This research aims in the future to help enhance inkjet printed deposit adhesion, resolution and quality whilst eliminating artefacts such as the coffee ring effect.
