Abstract
In this work we develop fast and locally photo-switching transition between rolling state (Cassie-Baxter (CB)) and sticky state (Wenzel (W)) using photo-switchable titanium dioxide (TiO2) deposited by atomic layer deposition (ALD). It takes 1 min of UV exposure for switching from CB to W and 5 min of dark storage in oven (200°C) to recover the surface energy. We use crystal nanocellulose (CNC) on T-shaped micro-pillars (micro-hoodoos [1] Figure1-j) to make hierarchical structures. Photo-masked UV exposure causes the locally transition from CB to W.
