Abstract
A solid organic material comprising at least one amphiphilic block copolymer of the methacrylic type, the block copolymer being dispersed in a polymer matrix, the block copolymer having a number-average molar mass (Mn) greater than or equal to 20 000 g/mol; a method for preparing said solid organic material; use of said solid organic material for antibacterial, antimicrobial, antiviral, anti-inflammatory and/or antifungal applications; a coating comprising said solid organic material.
Claims16
A solid organic material comprising at least one amphiphilic block copolymer of the methacrylic type, said amphiphilic block copolymer being dispersed in a polymer matrix and having a number-average molar mass (Mn) greater than or equal to 20 000 g/mol, wherein said amphiphilic block copolymer comprises at least one hydrophilic methacrylic block consisting of a first hydrophilic repeating unit being N,N-(dialkylamino)alkyl methacrylate and a second hydrophilic repeating unit being a quaternary ammonium ion of the latter,
- wherein the quaternary ammonium ion of the amphiphilic block copolymer is linked to a respective halide counterion.
A method for preparing a solid organic material comprising dispersing at least one amphiphilic block copolymer of the methacrylic type in a polymer matrix, wherein the at least one amphiphilic block copolymer has a number-average molar mass (Mn) greater than or equal to 20 000 g/mol, and comprises at least one hydrophilic methacrylic block consisting of a first hydrophilic repeating unit being N,N-(dialkylamino)alkyl methacrylate and a second hydrophilic repeating unit being a quaternary ammonium ion of the latter,
- wherein dispersing comprises one or more of extruding, injection molding, or curing.
A method, comprising:
- applying, to a surface susceptible to be exposed to bacteria, microbes, virus, fungi, a coating of the solid organic material, wherein the solid organic material comprises at least one amphiphilic block copolymer of the methacrylic type, said amphiphilic block copolymer being dispersed in a polymer matrix and having a number-average molar mass (Mn) greater than or equal to 20 000 g/mol, wherein said amphiphilic block copolymer comprises at least one hydrophilic methacrylic block consisting of a first hydrophilic repeating unit being N,N-(dialkylamino)alkyl methacrylate and a second hydrophilic repeating unit being a quaternary ammonium ion of the latter,
- wherein the quaternary ammonium ion of the amphiphilic block copolymer is linked to a respective halide counterion.
