Abstract
Contaminant-sequestering coatings include a network of hydrolyzed silane compounds including (i) a plurality of fluorinated functionalities, and (ii) a plurality of thiol functional groups are provided. The network of hydrolyzed silane compounds includes a fluorinated silane including (a) a hydrophilic polar head region. The polar head region includes one or multiple units of ethylene glycol (EG) functionality, (b) a fluorine-containing region, and (c) an anchor region including a silicon atom. The contaminant-sequestering coatings may sequester one or more per- and polyfluoroalkyl substances (PFAS), heavy metals, biological species, or any combination thereof.
