a Contact angles on the FS-SSM for various OLs including polar protic liquids, polar aprotic liquids, and nonpolar liquids. b Contact angles on the PR-SSM for above OLs. c Dependence of contact angle on the Ψp of the corresponding liquids (FS-SSM, each data is explained in Supplementary Table 4). d Left section: Digital photographs of different liquid droplets on the FS-SSM including dodecane (DOD), cyclohexane (CYH), and dichloromethane (DCM), water, formamide (FM), and ethylene glycol (EG); Right section: Digital photographs of the corresponding liquid droplets on the surface after the trigger of ethanol. e Dependence of contact angle on the Ψd of the corresponding liquids (PR-SSM, each data is explained in Supplementary Table 5). f Comparison of wetting performance of our membranes with some other notable reported membranes in the literature, taking formamide (FM) and tetrachloromethane (CCl4) as the research models. g Optimized geometries of model OL molecules binding with the amphoteric fluorosurfactant molecule by the density functional theory (DFT) calculations and the corresponding binding energy (ΔEb).
