Abstract
The present invention provides a composition comprising an antimicrobial bilayer coating on a substrate which coating comprises:
- (1) a polyionic material, in alternating layers, where one layer is a cationic polymer containing —NHR1 or —C(O)NHR2 groups, where R1 and R2 are independently hydrogen, straight- or branch-chain C1-C10 alkyl, phenyl, benzyl, or C6-C14 aryl; and another layer is an anionic polymer containing —COOH or —COOR groups, where R is straight- or branch-chain C1-C10 alkyl, phenyl, benzyl, or C6-C14 aryl; and(2) At least two full bilayers are coated on the substrate; and(3) the layers are crosslinked through amide, imide, urea, or carbamate bonds; and(4) at least 1% of the amine or amide N—H groups in the coating are converted to N—X, where X is Cl or Br.
