Keywords：Titanium alloy; bioinspired; Surface modification; Hydrophobicity; Fluoroalkylsilane; Abstract:TiO2 nano film with different nano structure were prepared on the surfaces of titanium TA1 and titanium alloy TC4 via electrochemical anodization.
The surface morphology was observed with SEM, and it is found that TiO2 films prepared on TA1 surface have porous structures, while the TiO2 films synthesized on TC4 surface look like nano rod.
It is concluded that both nano- structures and fluoroalkysilanes with low surface energy have play an important role in the wettability with the contact angle is more than 150o.The surface only have nano roughness without the low energy does not show superhydrophobicity.
In recent study ,it is reported that the wettability mechanism of the surface is effected by both the micro/nano structure of the surface and the chemical composition.
Since Titanium dioxide (TiO2) especially superhydrophilicity-superhydropjobicity of TiO2 surface with controlled structure and morphology has attracted great interest due to their potential applications in various technological fields.

Moreover, self-assembly strategies and hierarchical structures often found in Nature could inspire scientist and engineers to propose new solutions in the design and fabrication of surfaces with special features, such as wettability within extreme ranges, improved adhesion, optical and mechanical properties and specific bioactivity.
The observation of the materials produced by living organisms allow us to identify some common trends that could help in proposing bio-inspired strategies, that includes: (i) hierarchical organization of the structure - the biologically controlled growth of natural materials leads to highly multilevel architectures, exhibiting high control over the orientation of structural elements from the molecular level up to the final macroscopic structure; (ii) mild-processing conditions / green chemistry / selfassembly - the production of biomaterials is carried out through the self-assembling of elementary units at mild conditions of ambient temperature, neutral or physiological pH, always in aqueous environment; (iii) recurrent use of molecular constituents - widely variable properties are attained from apparently similar elementary units, such as amino acids in the production of proteins or the presence of calcium in many biogenic minerals; (iv) energy saving - biology uses
information and structure as the main vector for constructing materials, as compared with synthetic technologies based on larger usage of energy; (v) functionally graded properties - The properties and composition along the material may vary, gradually or abruptly, adapting to the local requirements; (vi) selfhealing and damage repair - some natural materials have the possibility to self-repair or remodel; (vii) biodegradability - natural materials are degraded either by hydrolytic mechanisms or through the enzymatic action.
Future developments should be based on increasing the focus in topics such as the understanding of fundamental biological mechanisms, nanoscience and nanotechnology and supramolecular chemistry.
