Bacteriostasis of a Super-Hydrophobic Micro-Porous Aluminum Surface by a Facile Preparation Method
We investigated the bacteriostasis of the super-hydrophobic surface on aluminum alloy by PP coating. The morphology of the surface was observed by a scanning electron microscopy. The contact angle (CA) was measured by an optical contact angle meter .Staphylococcus aureus and pathogenic escherichia coli adhesion on superhydrophobic surfaces were also evaluated. The inhibition ring test results show the inhibition of Escherichia coli and Staphylococcus aureus were 79.3% and 81.1%, respectively after 24 hours’ contact at 37oC, while the Quinn test demonstrates the surface possesses high resistance to bacterial contamination. The superhydrophobic surface is a factor to reduce device-associated infection and can be used in metal practice.
