Schematic illustration of (a) photopolymerization of the thiol-yne network at long wavelength. (b) Patterned and asymmetrical UV exposure to realize (c) a wedge-shaped surface area with a lengthwise wettability gradient, which is surrounded by the hydrophobic (not exposed and thus, not-cleaved) thiol-yne network. (d) Water contact angle and droplet movement on the irradiated surface (Adapted from reference [89] published by the Royal Society of Chemistry).
