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.
Claims16
A method of making a rechargeable antimicrobial anti-biofilm article comprising the steps of:
- adding one or more N-halamine biocidal compounds comprising one or more 3 to 10 membered rings and one or more nitrogen heteroatoms to a target material to be used directly or processed into a rechargeable antimicrobial anti-biofilm article.
A method of reducing the formation of biofilms on a surface comprising the steps of:
- adding one or more N-halamine biocidal compounds to a target material;
- and
- processing the target material into an article, wherein the one or more N-halamine biocidal compounds reduce the formation of biofilms on a surface of the article.
A biofilm-controlling and photo and thermal stabilizing additive comprising:
- a sterically hindered N-halo-amine with a molecular weight higher than 200 g/mol, wherein the composition provides anti-biofilm and thermal and photo stabilizing function.
