Antimicrobial materials

摘要

The disclosure provides methods and materials suitable for preparing coating layers on substrates. The coatings comprise quaternary amine groups and therefore impart anti-bacterial properties to the substrate. in one embodiment, for example, there is provided a quaternary amine-containing polymeric coating comprising propylene and ethylene repeat units.

主权项

1. A method for forming an anti-microbial surface coating on a substrate, the method comprising:
1) reacting a polymeric pre-amine material comprising a plurality of the functional groups, with an amine-containing reagent, comprising poly(ethyleneimine), so as to convert at least a portion of the functional groups to amine groups; and 2) reacting the amine groups from 1) with a quaternary amine conversion reagent, so as to convert at least a portion of the amine groups to quaternary amine groups.
