摘要： The present invention provides graft biocidal N-halamine polymers. The biocidal polymers are prepared by contacting precursor graft polymers with a halogen source. The precursor graft polymers are prepared by grafting a polymer, such as a polyolefin, with a vinyl monomer under suitable conditions, for example, a reactive extrusion condition. In one embodiment, the graft polymerization is carried out in the presence of a vinyl monomer and a radical initiator. The biocidal polymers have potent antimicrobial activities against a broad spectrum of microorganisms and virus, such as E. coli and flu viruses.

摘要： The present invention provides methods of making micron, submicron or nanometer dimension thermoplastic polymer microfibrillar composites and fibers, and methods of using the thermoplastic polymer microfibers and nanofibers in woven fabrics, biocidal textiles, biosensors, membranes, filters, protein support and organ repairs. The methods typically include admixing a thermoplastic polymer and a matrix material to form a mixture, where the thermoplastic and the matrix are thermodynamically immiscible, followed by extruding the mixture under conditions sufficient to form a microfibrillar composite containing a plurality of the thermoplastic polymer microfibers and/or nanofibers embedded in the matrix material. The microfibers and/or nanofibers are isolated by removing the surrounding matrix. In one embodiment, the microfibrillar composite formed is further extended under conditions sufficient to form a drawn microfibrillar and/or nanofibrillar composite with controlled diameters.

摘要： Quaternary ammonium salts were incorporated into anthraquinone dyes via a stable linkage. The structure of the antimicrobial colorants were characterized by Fourier Transform Infrared (FTIR), Nuclear Magnetic Resonance (NMR) and UV vis spectrometry. The dyes demonstrated excellent antimicrobial ability against both gram-negative and gram-positive bacteria in aqueous solution, as indicated by very low minimum inhibitory concentration (MIC). The colorants showed excellent stability in water under light, continuous heating as well as acidic and alkaline conditions.

摘要： The present invention provides functional finishing dyes comprising at least one functional finishing group covalently attached to a traditional dye via a chemical linkage. More particularly, the present invention provides novel antimicrobial cationic dyes comprising a quaternary ammonium salt group covalently attached to an aminoanthraquinioid dye via a linker. The dyes are particularly useful for imparting a functional property to a polymer, such as an antimicrobial, anti-static, softening, water-repellent, fire-resistant, soil-repellent, anti-UV, or anti-chemical property, and for simultaneously dyeing and finishing a polymer.

摘要： Highly porous nucleophilic organic cages (Nu-POC) were in-situ synthesized on cotton fibers by a condensation reaction between cyanuric chloride and melamine, and the products were employed as a robust wearable and flexible detoxifying protective material (denoted as POCotton) for vaporous pesticides. The covalent growth of Nu-POC particles on surfaces of cotton fibers retained the physical characteristics of Nu-POC to the greatest extend, which include specific surface area and porosity, while the cotton fabrics still remained wearable. The resultant POCotton can repeatedly adsorb fumigant vapors instantly (i.e., equilibrium reached within one minute) and massively (i.e., adsorption capacity at 596.88 mg/g of methyl iodide).
