Some embodiments include a method of preparing polymer nanofiber composites using a cross-linkable polymer precursor solvated with a solvent, and forming a nanofiber precursor by mixing with a metal-organic-framework (MOF) crystal material that includes a metal ion coupled to at least one multidentate ligand. Further, the method can include forming a plurality of nanofibers by electro-spinning the nanofiber precursor, where at least a portion of the nanofibers includes a dispersion of the first MOF crystal material. The method can include crosslinking the plurality of nanofibers by irradiating the plurality of nanofibers with UV light, IR light, visible light, gamma radiation, and/or electro-beam radiation. Further, the method can include applying a second MOF crystal material between the cross-linked nanofibers and the first MOF material.

UV protective fabrics and methods of making UV protective fabrics having ferulic acid and/or ferulic acid derivatives such as ethyl ferulate, including soaking the fabric in an aqueous solution of ferulic acid and/or a ferulic acid derivative, removing the fabric from the aqueous solution, and drying the soaked fabric. The aqueous solution may optionally include one or more surfactants. The ferulic acid and/or ferulic acid derivatives may provide UVA protection such as a UVA transmission of less than 5% and improved UPF such as a UPF of 50 or more, including fabrics which may have a dye, without changing the color of the fabric.

Methods of making polycationic nanofibers by grafting cationic polymers onto electrospun neutral nanofibers and polycationic nanofibers produced by the methods are provided herein. In addition, methods of using the polycationic nanofibers to reduce inflammation, to adsorb anionic compounds such as heparin or nucleic acids, to inhibit the growth of microbes or inhibit the formation of a biofilm are also provided. The polycationic nanofibers may be in a mesh and may be included in a medical device, wound dressing, bandage, or as part of a graft.

Various aqueous anti-pilling fabric treatment compositions are described. The compositions include one or more aqueous polyurethane dispersions or one or more acrylic polymers or both and a silicone. The compositions can be used treat fabrics, textiles and articles of manufacture made therefrom to impart anti-pilling properties to the same.

Described are polymer particles or polymer fibers covalently bonded to N-chloroamines, N,N-dichloroamines, N-chloro sulfonamides or N,N-dichloro sulfonamides, for removing volatile organic compounds (VOCs) from a space above a wound. The removal of said VOCs is believed to be primarily or predominantly by chemical reaction of the VOCs with the N-chloro or the N,N dichloro group as covalently attached to the polymer. In particular, the functionalized polymer particles or polymer fibers are part of a wound dressing and have the functionality to control, in particular reduce, odor emanating from wounds, without interacting with the wound. The described dressings can be advantageously used, in particular, in the treatment of chronic wounds or infected wounds.

Provided are MOF-fabric composites having a crystalline MOF adhered directly to fibers of the fabric and methods of making MOF-fabric composites. A solution is adsorbed onto a fabric. The solution can include a metal salt, a linker, and a solvent. The solution is adsorbed onto the fabric and the fabric suspended over a heated vapor. The vapor releases onto the fabric, causing the metal salt, the linker, and the solvent to diffuse out of the polymer fibers. The linker links metal from the metal salts to form crystals attached to the fabric, and the vapor aids crystallization.

A modified textile sorbent (MTS) material for direct capture of atmospheric CO.sub.2, and method for producing the same is disclosed. The MTS material includes a woven material and a sorbent polymer immobilized within the woven material, with the sorbent polymer having a plurality of swing-responsive moieties that respond to at least one of a temperature swing, a pressure swing, and a moisture swing. The method for producing a MTS material includes mixing a monomer of a sorbent polymer, in solution, with a woven material such that the monomer is impregnated into the woven material. The method also includes immobilizing the sorbent polymer within the woven material by polymerizing the monomer that is impregnated into the woven material. and substituting a counterion of the sorbent polymer with a swing-responsive moiety. The monomer is one of styrene-based, acrylate-based, methacrylate-based, silicone-based, or polysulfone-based.

The carbon fiber precursor fiber of the disclosure includes an acrylamide-based polymer fiber; and a self-crosslinked product of a self-crosslinking silicone oil on a surface of the acrylamide-based polymer fiber.

The present invention provides a skin-adhesive air-permeable intelligent bandage comprising: a stretchable adhesive antibacterial bioelectrical interface film made of stretchable adhesive antibacterial fibres; a waterproof moisture-permeable protective film for protecting the wound from external contaminants; and a permeable stretchable circuit assembly arranged between the bioelectrical interface film and the protective film. The permeable stretchable circuit assembly comprises: a permeable stretchable circuit board; one or more biosensors constructed on the permeable stretchable circuit board; and electronic components assembled on the permeable stretchable circuit board. The electronic components include: a physiological signal processing module electrically coupled to the one or more biosensors for in-situ wound monitoring; and a drug delivery actuation module electrically coupled to the bioelectrical interface film for adaptive drug delivery for wound treatment. The provided bandage is more convenient, comfortable and efficient without numerous dressings, thereby not hindering the daily activities and life quality of patients.
