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.
