Herein, antibacterial coatings and methods of making the antibacterial coatings are described. A first branched polyethyleneimine (BPEI) layer is formed and a first glyoxal layer is formed on a surface of the BPEI layer. The first BPEI layer and the first glyoxal layer are cured to form a crosslinked BPEI coating. The first BPEI layer can be modified with superhydrophobic moieties, superhydrophilic moieties or negatively charged moieties to enhance the antifouling properties of the coating. The first BPEI layer can be modified with contact-killing bactericidal moieties to enhance the bactericidal properties of the coating. |
