Claim 6:
7. A composition comprising:
I) about 0.1 wt. % to about 30 wt. % of:
A. a surface-active moiety covalently linked to a copolymer of hydroxyethylpyrrolidone methacrylate/glycidyl methacrylate, wherein the copolymer has the structure:, wherein R is hydrogen or an alkyl, a and b are mole %, the sum is less than 100; or

B. a hydroxyethylpyrrolidone methacrylate/glycidyl methacrylate copolymer that is covalently linked to a surface-active moiety having the structure:, wherein R is hydrogen or an alkyl, a and b are numbers, mole %, the sum is less than 100; M is the surface-active moiety, and

II) about 1.0 wt. % to about 99 wt. % of at least one additive;
wherein the surface-active moiety in either A. or B. is selected from the group consisting of:
a. organic moieties selected from the group consisting of:
i. natural moieties selected from the group consisting of biofunctional peptide, protein, glycol-protein, lipo-protein, polypeptide, DNA, RNA, and a pharmaceutical active, and/or
ii. synthetic moieties selected from the group consisting of maleic anhydride-copolymer, itaconic anhydride copolymer, maleic acid-copolymer, itaconic acid-copolymer, polyterphtalate, polyalkyd, polyester, polyurethane, polyether, epoxy, nylon, poly(meth)acrylate, polyolefin, polyvinyl ether, polystyrene a pharmaceutical active, and a sunscreen active; and/or

b. modified allotrope moieties selected from the group consisting of modified graphene, modified fullerenes, modified carbon nanotube, modified graphite, and modified carbon black.
