Adsorption of alginate and albumin on aluminum coatings inhibits adhesion of Escherichia coli and enhances the anti-corrosion performances of the coatings

- Adsorption behaviors of alginate and albumin on Al coatings were investigated at molecular level.
- The adsorption inhibits effectively the colonization of Escherichia coli bacteria.
- The adsorption alters the wettability of the Al coatings.
- The conditioning layer enhances anti-corrosion performances of the Al coatings.
