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.
