Micropatterning of functional dye films on wettability-patterned surfaces using soft liquid-phase adsorption

- This technique allows for the fabrication of dye films on wettability-patterned surface.
- Thickness of rhodamine B films increased with a decrease in immersion temperature.
- Thickness of rhodamine B films increased with an increase in immersion angle.
- Thickness of films fabricated by this technique is larger than that of films by other techniques.
- Thymol blue films serve as pH-responsive devices under exposure to HCl and NH3 gases.
