I don't understand the paragraph below, so I want to know the principles of using the Cassie-Baxter wetting state and Wenzel wetting state mentioned in this paragraph. This paragraph is an excerpt from 'Haechler, Iwan, et al. "Transparent sunlight-activated antifogging metamaterials." Nature Nanotechnology (2022): 1-8.'

"Due to the low surface energy and texture of these surfaces, the condensed droplets retain high mobility (CassieBaxter wetting state) and thus avoid the pinning of water droplets on the surface (Wenzel wetting state). However, when exposed to environments with high relative humidity, sophisticated engineering of the structurewhich is neither readily robust nor easily upscalable on glassis imperative, as nanoscale nucleation within the textures eradicates the CassieBaxter state, inducing the Wenzel state and destroying the surfaces superhydrophobic characteristics.
