Abstract:
The present invention is a composition and method for making and using a rechargeable multifunctional additive that reduce the formation of biofilms on a surface, the additive can also remain photo and thermally stable by synthesizing one or more N-halamine compounds and adding one or more N-halamine biocidal compounds to a target material prior, during or after the target material is made. The resultant material can be used directly to provide antimicrobial functions and control biofilm formation, or the material can be further processed into an article.
Abstract:
The present invention provides heterocyclic vinylic compounds that can be used to form biocidal polymers. The polymers thus generated can used alone or can be grafted onto textiles, fabrics and polymers. The polymers are readily converted to N-halamine structures on exposure to a halogen source such as commercially available chlorine bleach. The N-halamine derivatives exhibit potent antibacterial properties against microoganisms and these properties are durable and regenerable.
Abstract:
The invention relates to polymeric systems for stabilizing, storing and delivering hypohalide salts. One system consists of material coated with two layers: one prepared from polyethylene glycol epoxide and melamine solution and second prepared from inorganic hypohalide salt solution. The material can be fabric, cotton, bamboo, cellulosic materials, blend of cellulosic and synthetic fibers. Antimicrobial materials comprising this system are also described. Another system consists of material containing pre-formed spaces coated with water-polyethylene glycol solution of hypohalide salt and encapsulated by film forming polymer. Hypohalide salts within both systems are in some cases storage stable for at least three months.
Abstract:
The present invention includes methods and compositions for providing rechargeable aliphatic N-halamine polymers, monomers, copolymers additives and coatings. The rechargeable aliphatic N-halamine includes an aliphatic N-halamine compound exchangeable associated with one or more halides.
Abstract:
The present invention includes compositions, articles, methods controlling microbial contamination of a surface by functionalizing a surface of an object and binding one or more acyclic-amine structures to the surface. The one or more acyclic-amine structures are halogenated to form one or more acyclic N-halamine structures. The one or more acyclic N-halamine structures modulate the formation of a biofilm.
Abstract:
Biocidal compounds have been synthesized and tested. These biocidal compounds have broad-spectrum efficacy and their biocidal properties are easily renewable. Illustrative examples of these biocidal compounds include N-halamine monomers and polymers and silver sulfadiazine polymers. These compounds can be used to add biocidal function to various materials and articles.
Abstract:
The present invention includes methods, articles, compositions and colorant dyes and pigments that include biocidal N-halamine dye composition having two or more heterocyclic ring structures attached to one or more N-halamine groups, wherein one or more halogens associate with the one or more one or more N-halamine groups to affect biocidal activity.
