Claims30
A fiber-based composite comprising:
- a network comprising a multiplicity of fibers;
- and
- a coating on the multiplicity of fibers, wherein the coating comprises:
- one or more compounds of Formula IA;
- and
- one or more compounds of Formula IIA,
- wherein a ratio of a total weight of the one or more compounds of Formula IA to a total weight of the one or more compounds of Formula IIA is in a range of 1:1 to 99:1,
- Formula IA is:
- or a salt thereof when R is C1-C6 alkyl optionally substituted with one or more of OH and C1-C6 alkoxy,
- wherein:
- R is selected from the group consisting of H and C1-C6 alkyl optionally substituted with one or more of OH and C1-C6 alkoxy;
- R1, R2, R3, R4, R5, R6, R7, R8, and R9 are independently selected from the group consisting of:
- H, OH, C1-C6 alkyl, C2-C6 alkenyl, and C1-C6 alkoxy;
- each occurrence of R10A, R10B, R11A, and R11B is independently selected from the group consisting of:
- H, OH, C1-C6 alkyl, C2-C6 alkenyl, and C1-C6 alkoxy;
- any two R1, R2, R3, R4, R5, R6, R7, R8, R9, R10A, R10B, R11A, and R11B on adjacent carbon atoms can be taken together with the carbon atoms to which they are attached to form a double bond, a 3- to 6-membered ring heterocycle, or a C3-C6 cycloalkyl;
- o is an integer from 0 to 17;
- p is an integer from 0 to 17;
- and
- the sum of o and p is from 0 to 17, and
- Formula IIA is:
- wherein:
- R1, R2, R3, R4, R5, R6, R7, R8, and R9 are independently selected from the group consisting of:
- H, OH, C1-C6 alkyl, C2-C6 alkenyl, and C1-C6 alkoxy;
- and
- each occurrence of R10A, R10B, R11A, and R11B is independently selected from the group consisting of:
- H, OH, C1-C6 alkyl, C2-C6 alkenyl, and C1-C6 alkoxy;
- any two R1, R2, R3, R4, R5, R6, R7, R8, R9, R10A, R10B, R11A, and R11B on adjacent carbon atoms can be taken together with the carbon atoms to which they are attached to form a double bond, a 3- to 6-membered ring heterocycle, or a C3-C6 cycloalkyl;
- o is an integer from 0 to 17;
- p is an integer from 0 to 17;
- the sum of o and p is from 0 to 17;
- Xn+ is a cationic moiety having formal charge n;
- and
- wherein a surface of the fiber-based composite is hydrophobic and lipophobic.

A method of making a fiber-based composite, the method comprising:
- combining a multiplicity of fibers and a liquid to yield a slurry;
- combining one or more compounds of Formula IA with the slurry;
- removing some of the liquid from the slurry to yield a fibrous mass;
- and
- drying the fibrous mass, wherein drying the fibrous mass comprises polymerizing the one or more compounds of Formula IA, thereby forming a polymer in contact with the multiplicity of fibers to yield the fiber-based composite,
- wherein a surface of the fiber-based composite is hydrophobic and lipophobic, and
- Formula IA is:
- or a salt thereof when R is C1-C6 alkyl optionally substituted with one or more of OH and C1-C6 alkoxy,
- wherein:
- R is selected from the group consisting of H and C1-C6 alkyl optionally substituted with one or more of OH and C1-C6 alkoxy;
- R1, R2, R3, R4, R5, R6, R7, R8, and R9 are independently selected from the group consisting of:
- H, OH, C1-C6 alkyl, C2-C6 alkenyl, and C1-C6 alkoxy;
- each occurrence of R10A, R10B, R11A, and R11B is independently selected from the group consisting of:
- H, OH, C1-C6 alkyl, C2-C6 alkenyl, and C1-C6 alkoxy;
- any two R1, R2, R3, R4, R5, R6, R7, R8, R9, R10A, R10B, R11A, and R11B on adjacent carbon atoms can be taken together with the carbon atoms to which they are attached to form a double bond, a 3- to 6-membered ring heterocycle, or a C3-C6 cycloalkyl;
- o is an integer from 0 to 17;
- p is an integer from 0 to 17;
- and
- the sum of o and p is from 0 to 17.
