  • Analysis of lamellar deformation by liquid droplets and shape-memory recovery.

    • Main Results:

    • Surfaces with lamellae aspect ratios up to 57:1 were successfully fabricated.
    • Wetting properties were found to be temperature-dependent, with easier wetting at elevated temperatures due to increased lamellar deformability.
    • Droplet-induced lamellar deformation could be temporarily fixed at low temperatures and restored upon heating above the polymer's transition temperature.

    Conclusions:

    • High-aspect-ratio lamellar surfaces fabricated from shape-memory polymers exhibit tunable wetting properties controlled by temperature.
    • The ability to deform and recover shape allows for novel, thermally controlled microfluidic elements, such as smart valves.
    • This research opens new avenues for designing responsive microfluidic systems with applications in lab-on-a-chip devices and beyond.
