| Abstract: | n‐Hexadecanoic acid (HA) and α‐hydroxyl n‐hexadecanoic add (HHA) are shown to spontaneously assemble on Si‐supported titanium surfaces. Contact angle measurements, reflection absorbance IR, AFM and XPS characterizations are performed to examine the physical and chemical states of attached monolayers. The results show that the two amphiphiles tend to form disordered monolayers on titanium surfaces. The HHA headgroups are believed to form polydentate coordination with Ti, which is more chemically stable than the bidentate coordination of HA. All the facts of characterization indicate that HHA monolayer has more surface coverage than HA monolayer. |
