Mechanically durable, superomniphobic artificial leather surfaces with biofouling-resistant properties by dip-coating technique |
| 초록 |
In the rise in demand for healthcare, the ability of material resist to bacterial contamination has become important. Therefore, we studied a superomniphobic coating by using fluorinated silica nanoparticles in a single-step procedure and achieved durable anti-biofouling and self-cleaning surface. Among the various materials, we chose the artificial leather as substrate because of its diverse applications and the increasing demand in global. The contact angle of water and oil was increased to θwater = 164.0°and θoil = 160.6°. The bacterial anti-adhesive properties were confirmed with Escherichia coli and S. epidermidis and bacteria attachment on superomniphobically-modified surfaces was reduced more than 99.0% in comparison to bare artificial leather surfaces. Also, self-cleaning property with various contaminants was lasted after the adhesion test. We anticipate this study can significantly eliminate potential risks associated with various cross-contamination scenarios. |
