Abstract

Embodiments of the present disclosure, in one aspect, relate to structures having a polymer composition covalently bonded to the surface of the structure, methods of attaching the polymer to the surface of the structure, methods of decreasing the amount of microorganisms formed on a structure, materials, methods of attaching materials, and the like.

First claim

Therefore, at least the following is claimed:

1. A structure, comprising:
a surface having a polymer covalently attached to the surface, wherein the structure has an antimicrobial characteristic; and
wherein the polymer is a linear or branched polyethylenimine polymer that has been quaternized with a hydrophobic side chain moiety (R1) and a photo cross-linkable moiety (B), wherein the polymer is covalently bonded to the surface through the photo cross-linkable moiety, wherein the linear or branched polyethylenimine polymer has the following structure:

wherein R2 is a linking moiety and is a hydrocarbon carbon chain that includes 3 to 20 carbons and includes one or more double or triple bonds, wherein the R2 is substituted or unsubstituted, and wherein “m” and “n” are each independently 1 to 1000; wherein R1 is saturated and includes 1 to 20 carbons and is substituted or unsubstituted.

2. The structure of claim 1 , wherein the structure is selected from the group consisting of: a fabric, a textile article, a natural fiber, a synthetic fiber, a porous membrane, a plastic structure, an oxide structure having a functionalized layer on the surface of the structure, a metal structure having a functionalized layer on the surface of the structure, a glass structure having a functionalized layer on the surface of the structure, and a combination thereof.

3. The structure of claim 1 , wherein the photo cross-linkable moiety is selected from the group consisting of: an aryl ketone, an aryl azide group, a diazirine group, and a combination thereof.

4. The structure of claim 3 , wherein the aryl ketone is selected from the group consisting of: an acetophenone, an acetophenone derivative, a benzophenone, a benzophenone derivative, a naphtylmethylketone, a dinaphtylketone, a dinaphtylketone derivative, and a combination thereof.

5. The structure of claim 4 , wherein the photo cross-linkable moiety is 4-[(6-Bromohexyl) oxy] benzophenone.

6. The structure of claim 1 , wherein the interaction of the polymer with UV light causes the polymer to covalently bond with the surface.

7. The structure of claim 1 , wherein R1 is selected from the group consisting of: octane, decane, dodecane, tridecane, pentadecane, hexadecane, heptadecane, octadecane, nonadecane, eicosane, heneicosane, docosane, tetraconsane, hexane, heptane, nonane, undecane, tricosane, a derivative of each, and a combination thereof.

8. A structure, comprising:
a surface having a polymer covalently attached to the surface, wherein the structure has an antimicrobial characteristic; and
wherein the polymer is a linear or branched polyethylenimine polymer that has been quaternized with a hydrophobic side chain moiety (R1) and a photo cross-linkable moiety (B), wherein the polymer is covalently bonded to the surface through the photo cross-linkable moiety, wherein the linear or branched polyethylenimine polymer has the following structure:

wherein R1 is selected from the group consisting of: octane, decane, dodecane, tridecane, pentadecane, hexadecane, heptadecane, octadecane, nonadecane, eicosane, heneicosane, docosane, tetraconsane, hexane, heptane, nonane, undecane, tricosane, a derivative of each, and a combination thereof, wherein R2 is a linking moiety and is a hydrocarbon carbon chain that includes 3 to 20 carbons and includes one or more double or triple bonds, wherein the R2 is substituted or unsubstituted, and wherein “m” and “n” are each independently 1 to 1000.

9. The structure of claim 8 , wherein the photo cross-linkable moiety is a benzophenone.

10. The structure of claim 8 , wherein the photo cross-linkable moiety is an acetophenone.

11. The structure of claim 8 , wherein the photo cross-linkable moiety is a naphtylmethylketone.

12. The structure of claim 8 , wherein the photo cross-linkable moiety is a dinaphtylketone.
