Abstract:
1. An antimicrobial bandage material comprising; a. a first substrate; b. an antimicrobial superabsorbent polymer, wherein said superabsorbent polymer is non-leachably bound to said first substrate, and wherein said superabsorbent polymer imparts antimicrobial activity to the bound said first substrate; c. a second substrate; d. a non-superabsorbent polymer, wherein said non-superabsorbent polymer is non-leachably bound to said second substrate, and wherein said non-superabsorbent polymer imparts antimicrobial activity to the bound said second substrate; wherein said second substrate and bound non-superabsorbent polymer covers or surrounds said first substrate and bound superabsorbent polymer, wherein said superabsorbent polymer consists essentially of polymers of a first monomeric quaternary ammonium salt and at least one cross linking agent, wherein said non-superabsorbent polymer consists essentially of polymers of a second monomeric quaternary ammonium salt, and wherein said first monomeric quaternary ammonium salt and second monomeric quaternary ammonium salt are selected, independently, from the group consisting of [2-(methacryloxloxy)ethyl]trimethylammonium chloride, also known as TMMC, [2-(acryloyloxy)ethyl]trimethylammonium methyl sulfate, also known as TMAS, [2-(acryloyloxy)ethyl)trimethylammonium chloride, also known as TMAC, [3-(methacryloylamino) propyl]trimethylammonium chloride, also known as TMAPMC, vinylbenzyltrimethylammonium chloride, also known as VBTAC, and diallyldialkylammonium salts.
