摘要：
Embodiments are directed to a method of making an antifouling and bactericidal coating with tailorable surface topology. The method includes depositing a layer of branched polyethyleneimine (BPEI) and diamino-functionalized poly(propylene oxide) (PPO) in a mixture of water and organic solvent on a substrate to form a layer of BPEI/PPO. The method includes depositing a layer of glyoxal in a water-containing solution on the layer of BPEI/PPO. The method further includes curing the layer of BPEI/PPO and layer of glyoxal to form a homogenous, glyoxal crosslinked BPEI/PPO coating, where the curing induces local precipitation and alteration of the glyoxal crosslinked BPEI/PPO coating to provide a textured surface.
