Production and analysis of stable microfluidic devices with tunable surface hydrophilicity via the in-situ tertiary-amine catalyzed Michael addition of a multifunctional thiol to a multifunctional acrylate

The Use of Click-Type Reactions in the Preparation of Thermosets

“…Stable and tunable hydrophilic-surfaced materials for microfluidic applications were also obtained by Pojman et al [220] via the in situ, tertiary-amine-catalyzed Michael addition of a multifunctional thiol to a multifunctional acrylate. As shown in Figure 8, a complete microfluidic device was obtained, demonstrating the potential of these systems in microfluidics.…”

Transient Superhydrophilic Surface Modification of Polyimide by Metal Ion Beam Irradiation

“…Superhydrophilic surface modification is applied in various fields, ranging from material science and surface engineering to biomedical devices, electronics, electrochemistry, oil emulsion purification, and energy-related technologies. − Superhydrophilic surfaces exhibit a strong affinity for liquids, including water, enabling the liquid to spread quickly and evenly over the surface. This property enhances capillary action and has applications in microfluidic devices and absorbent products. − Additionally, this property can prevent the formation of fog and ice on surfaces − and improve heat transfer efficiency by increasing the contact area between a heated surface and the cooling liquid. − Recently, superhydrophilic surface modification has been employed in the fabrication process of printed electronics and flexible display panels, − particularly for the substrates of such panels, which are typically made of polymers such as polyimide (PI), polyethylene terephthalate (PET), and poly­(ethylene naphthalate) (PEN).…”
