1. A thermoset omniphobic composition comprising:
a thermoset polymer comprising a polymerization reaction product between: an ethylenic-polyfunctional first monomer, and optionally an ethylenic-functional second monomer which is different from the ethylenic-polyfunctional first monomer;
an omniphobic polymer comprising a copolymer between: an ethylenic-functional omniphobic third monomer, and an ethylenic-functional fourth monomer different from the third monomer; and
at least one filler distributed throughout the thermoset polymer, the filler being selected from the group consisting of nanoclay, graphene oxide, graphene, silicon dioxide (silica), aluminum oxide, cellulose nanocrystals, carbon nanotubes, titanium dioxide (titania), diatomaceous earth, and combinations thereof;
wherein a combined amount of the thermoset polymer, the omniphobic polymer, and the at least one filler is at least 95 wt. % of the thermoset omniphobic composition.
