Abstract
Functionalized textile materials are provided. At least a portion of a textile surface in includes a ceramic material, such as a binderless porous structured ceramic, and optionally, one or more functional layer is applied, resulting in a textile material with one or more desirable functional properties, such as hydrophilicity, hydrophobicity, flame retardancy, photocatalysis, anti-fouling, and/or deodorant properties.
Claims16
A composition comprising a binderless ceramic material on a porous polymeric substrate,
- wherein the composition comprises a partially filled porous structure wherein pores of the porous polymeric substrate are partially filled with the ceramic material, wherein the ceramic material is directly bonded to the porous polymeric substrate, and wherein the partially filled porous structure is modified with a functional layer,
- wherein the porous polymeric substrate comprises a woven material, a knitted material, a nonwoven fabric or textile, or paper,
- wherein the functional layer comprises a molecule with a head group and a tail group and imparts a hydrophobic property to the composition,
- wherein the head group of the functional molecule comprises a silane group, a phosphonate group, a phosphonic acid group, a carboxylic acid group, an alcohol group, a hydroxyl group, a thiolate group, a thiol group, and/or an ammonium group, and
- wherein the tail group of the functional molecule comprises a hydrocarbon group, a fluorocarbon group, a vinyl group, a phenyl group, an epoxide group, an acrylic group, and/or an acrylate group.
