Abstract
The present disclosure provides a textile coating composition comprising a primer bonding to at least one surface of a textile and a polymer brush bonding to the primer. The primer is of general formula (I) and the polymer brush is of general formula (II). A coated textile comprising a textile coated with the textile coating composition and a method of forming the coated textile are also provided.
Claims20
A textile coating composition comprising:
- a primer bonding to at least one surface of a textile, wherein the primer is of general formula (I)
- wherein R1 forms a bond with the at least one surface and is selected from the group consisting of amine, alkoxy, hydroxy, acid, acrylate, halide, ester, ether, alcohol, vinyl, carboxylic, carbonyl, amino, and mercapto;
- R2 is selected from the group consisting of alkyl, aryl, siloxane and any combinations thereof;
- and
- R3, R4 and R5 are each independently hydroxy, alkoxy optionally substituted with an alkoxy, siloxy, halide or alkyl, with the proviso that R3, R4 and R5 are not simultaneously alkyl;
- and
- a polymer brush forming a bond with at least one of R3, R4 and R5 of the primer, wherein the polymer brush comprises a polymer having an oxygen-containing backbone and having a glass transition temperature less than about 20° C.
4 more elements
A coated textile comprising:
- a textile;
- a primer layer bonding to at least one surface of the textile, wherein the primer layer comprises a primer of general formula (I)
- wherein R1 forms a bond with the at least one surface and is selected from the group consisting of amine, alkoxy, hydroxy, acid, acrylate, halide, ester, ether, alcohol, vinyl, carboxylic, carbonyl, amino, and mercapto;
- R2 is selected from the group consisting of alkyl, aryl, siloxane and any combinations thereof;
- and
- R3, R4 and R5 are each independently hydroxy, alkoxy optionally substituted with an alkoxy, siloxy, halide, or alkyl, with the proviso that R3, R4 and R5 are not simultaneously alkyl;
- and
- a polymer brush layer overlaying the primer layer, wherein the polymer brush layer comprises a polymer brush forming a bond with at least one of R3, R4 and R5 of the primer, wherein the polymer brush comprises a polymer having an oxygen-containing backbone and having a glass transition temperature less than about 20° C.
5 more elements
A method of forming a coated textile, comprising:
- depositing a primer layer on a surface of a textile to form a textile surface coated with the primer layer, wherein the primer layer comprises a primer of general formula (I)
- wherein R1 forms a bond with the at least one surface and is selected from the group consisting of amine, alkoxy, hydroxy, acid, acrylate, halide, ester, ether, alcohol, vinyl, carboxylic, carbonyl, amino, and mercapto;
- R2 is selected from the group consisting of alkyl, aryl, siloxane and any combinations thereof;
- and
- R3, R4 and R5 are each independently hydroxy, alkoxy optionally substituted with an alkoxy, siloxy, halide, or alkyl, with the proviso that R3, R4 and R5 are not simultaneously alkyl;
- and
- depositing a polymer brush layer on the textile surface coated with the primer layer to form the coated textile, wherein the polymer brush layer comprises a polymer brush forming a bond with at least one of R3, R4 and R5 of the primer, wherein the polymer brush comprises a polymer having an oxygen-containing backbone and having a glass transition temperature less than about 20° C.;
- wherein the coated textile exhibits a friction coefficient of less than about 0.35.
