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.

N-halamines compounds as multifunctional additives

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.

N-halamine-based rechargeable biofilm-controlling tubular devices, method of making and using

The present invention includes compositions and methods of making an antimicrobial polymer by mixing sterically hindered N-halo-amines with polymeric materials with a source of halides selected from sodium di-X-isocyanurate, sodium hypohalite, N&#x2014;X-succinimide, and calcium hypohalite, and mixtures and combinations thereof, wherein X is selected from Cl or Br, and wherein the sterically hindered halo-amines are charged before or after mixing with the polymers, or combinations thereof.
