1. A biofilm-controlling and photo and thermal stabilizing additive comprising:
- a sterically hindered N-halo-amine comprising a 2,2,6,6-tetramethyl-N-halo-piperidinyl ring moiety directly connected to an aliphatic chain, with a molecular weight higher than 200 g/mol, wherein the 2,2,6,6-tetramethyl-N-halo-piperidinyl ring moiety does not include a spirocyclic group, andwherein the composition provides anti-biofilm and thermal and photo stabilizing function.

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.
