1. An aqueous precursor liquid for forming an odor-absorbing and anti-fouling heterophasic thermoset polymeric coating, wherein the aqueous precursor liquid comprises:
a fluorine-containing precursor having a functionality greater than about 2 that forms a fluorine-containing polymer component defining a first phase in the anti-fouling heterophasic thermoset polymeric coating;
a first precursor that forms a first component comprising a cyclodextrin, wherein the first component defines a second phase in the odor-absorbing and anti-fouling heterophasic thermoset polymeric coating;
a crosslinking agent comprising a moiety selected from the group consisting of an amine moiety, a hydroxyl moiety, an isocyanate moiety, and a combination thereof, wherein the crosslinking agent is capable of bonding at least a portion of the fluorine-containing polymer component in the first phase with at least a portion of the first component in the second phase;
water; and
optionally, an acid or a base;
wherein the first phase is a continuous phase and the second phase is a first discrete phase within the continuous phase, wherein the first discrete phase comprises a plurality of first domains each having an average size of greater than or equal to about 100 nm to less than or equal to about 5,000 nm; or
wherein the second phase is the continuous phase and the first phase is the first discrete phase within the continuous phase, wherein the first discrete phase comprises a plurality of first domains each having an average size of greater than or equal to about 100 nm to less than or equal to about 5,000 nm.
