The present disclosure relates to an amphiphilic copolymer comprising:
a) repeating monomeric units comprising a pendant zwitterionic moiety;
b) repeating monomeric units comprising a pendant group comprising a fluorine-containing group and at least one heteroatom; and
c) optionally, secondary repeating monomeric units comprising a pendant group comprising a functional group selected from the group consisting of phosphate groups, phosphonate groups, sulfonate groups, alkoxysilane groups, carboxylate groups, and any combinations thereof;
and wherein the repeating monomeric units of the amphiphilic copolymer independently comprise an ethylenically unsaturated polymerizable group selected from the group of (meth)acrylate ester containing groups.
In another aspect, the present disclosure is directed to a protective coating composition comprising:
a) an amphiphilic copolymer as described above, and
b) a solvent comprising water.
