Effect of surface topological structure and chemical modification of flame sprayed aluminum coatings on the colonization of Cylindrotheca closterium on their surfaces

- Multi-layer coating structure was constructed by flame spray and modification.
- Micropatterned structure deteriorates the settlement of diatoms.
- Modification by Zwitterionic molecules further enhances the antimicrobial ability.
- Micropatterning and surface chemistry do not show remarkable synergistic effect.
