ABSORBENT MATERIALS WITH COVALENTLY-BONDED, NONLEACHABLE, POLYMERIC ANTIMICROBIAL SURFACES, AND METHODS FOR PREPARATION

This invention relates to methods and compositions for materials having a non-leaching coating that has antimicrobial properties. The coating is applied to substrates such as gauze-type wound dressings, powders and other substrates. Covalent, non-leaching, non-hydrolyzable bonds are formed between t...

Beschreibung
Zusammenfassung:	This invention relates to methods and compositions for materials having a non-leaching coating that has antimicrobial properties. The coating is applied to substrates such as gauze-type wound dressings, powders and other substrates. Covalent, non-leaching, non-hydrolyzable bonds are formed between the substrate and the polymer molecules that form the coating. A high concentration of anti-microbial groups on multi-length polymer chains and relatively long average chain lengths, contribute to an absorbent or superabsorbent surface with a high level antimicrobial efficacy. L'invention concerne des procédés et des compositions qui permettent de fabriquer des matériaux de revêtement ayant des surfaces non lixiviables à propriétés anti-microbiennes. Ce type de matériau de revêtement est appliqué à des substrats comme les pansements de gaze, les poudres et autres substrats. On établit des liaisons covalentes non hydrolysables, ne se prêtant pas à la lixiviation, entre le substrat et les molécules polymères constituant le revêtement. Une forte concentration de groupes anti-microbiens sur des chaînes polymères de longueurs multiples ainsi que des longueurs de chaîne moyennes relativement importantes contribuent à établir une surface absorbante ou superabsorbante qui présente un niveau élevé d'efficacité anti-microbienne.
