Abstract
The surface wettability of plants exhibits many unique advantages, which enhances the environmental adaptability of plants. In view of the rapid development of responsive materials, smart surfaces have been explored extensively to regulate surface wettability through external stimuli. Herein, we summarized recent advancements in bioinspired surfaces with switchable wettability. Typical bioinspired surfaces with switchable wettability and their emerging applications have been reviewed. In the end, we have discussed the remaining challenges and provided perspective on future development.

The surface wettability of plants exhibits unique advantages (Wu et al, 2009, 2010, 2011a,b; Jiang et al, 2011), which enhances the environmental adaptability and improves survival chances. (Zhang et al, 2012a, 2019b, 2020; Yong et al, 2017) For example, water droplets roll freely on the surface of lotus leaves, which shows self-cleaning characteristics (Figure 1a; Zhang et al, 2012c)
Benefiting from temperature responsive shape memory polymer (SMP) materials, Cheng et al have successfully developed thermal response surfaces that tune superhydrophobic characters between isotropic and anisotropic state (Cheng et al, 2018)
