Abstract
The present disclosure relates materials and methods related to the removal of polyfluorinated alkyl compounds from water. More specifically, the materials disclosed herein are fluoroolefin-vinyl ether copolymer containing fluorinated ionic polymer networks which can be used to remove the polyfluorinated alkyl compounds from water.
Claims31
A fluorinated ionic polymer network comprising a fluoroolefin-vinyl ether copolymer and at least one crosslinking agent, wherein the fluorinated ionic polymer network has the structure of Formula (III):
- wherein
- Y is, in each instance, a crosslinking agent, absent, a leaving group, or a leaving group precursor, provided that in at least one instance, Y is the crosslinking agent, wherein
- the crosslinking agent comprised nucleophilic moieties prior to incorporation into the fluorinated ionic polymer network,
- the leaving group is selected from the group consisting of halo CN, S-aryl, N3, O-aryl, and O—SO2R4, wherein R4 is lower-alkyl, aryl or aryl lower-alkyl, wherein the alkyl or aryl groups are unsubstituted, or mono- or di- substituted with halides, SO2R4, SOR4, COOR4, COR4, CN, CF3, or NO2, and
- the leaving group precursor is a group capable of being converted into a leaving group, such as —SH, —OH, —SR5, or —OR5, wherein R5 is a protecting group,
- n is an integer from 1-2000,
- R1 is, in each instance, independently chosen from substituted or unsubstituted C1-C10 alkyl, substituted or unsubstituted aryl, substituted heteroaryl, substituted cycloalkyl, wherein the substituted or unsubstituted C1-C10 alkyl may further comprise an ether, amide, ester, amine, thioether, or a combination thereof, and
- X is, in each instance, chosen from —F, —Cl, —CF3, —CF2CF3, and —CF2H.

The method of claim 125, wherein the crosslinking agent is heteroaliphatic and the nucleophilic moieties are each independently selected from the group consisting of —OH, —NH2, —NHR, and —NRaRb, where Ra and Rb are alkyl.
