Permanent, Antimicrobial Surface Modifications
Application(Product)Methodsand compositions to modify virtually any surface rendering it withantimicrobial characteristics ProblemsAddressed (benefits/advantages)Microbial contamination is one of the most serious concerns inseveral areas of life such as textiles, food packaging, processing and storage,water purification, medical devices, drugs and dental surgery equip-ment.Recently antimicrobial agents have gained more interested from both academicand industrial points of view because of their potential to provide safetybenefits to many mate-rials. Currently, antimicrobials are presented as washesand as blends with other materials. These forms do not warrant permanent and/oreconomically viable solutions for many appli-cations. A few literature reportsconcerning the preparation of antimicrobial surfaces via the covalent couplingof poly quaternary ammonium (PQA) compounds to a variety of surfaces has beendemonstrated. The covalent attachment of biocidal polymers on common and inertplastic surfaces however, is much more challenging due to the lack of reactivefunctional groups.
